Evaluation of Common Bean (Phaseolus vulgaris) Genotypes for Resistance to Root Rot Disease Caused by Pythium aphanidermatum and Pythium splendens under Screen House

Journal of Natural Sciences Research (2016)

Papias Binagwa C.K. Bonsi Susan Nchimbi Msolla

The most important economic species of the genus Phaseolus is the common beans ( Phaseolus vulgaris L.) which is widely cultivated and arguably the most significant leguminous for direct human consumption. It is an important source of dietary protein, calories, dietary fibres and minerals particularly iron and zinc. Root rot disease caused by Pythium pathogen is one of the major production constraint in bean growing areas within East Africa. In Tanzania, control measures used by farmers are fungicidal seed treatments which are less effective and not environmentally friendly, soil drainage and crop rotation which are not sustainable in the disease management. This study focused on the evaluation and selection of promising common bean genotypes for resistance to Pythium root rot disease from 100 bean genotypes sourced from Tanzania, CIAT and Andean Diversity Panel (ADP). Inoculum of Pythium aphanidermatum and Pythium splendens were used for challenging the beans genotypes under controlled environment. Experiment was set by randomized completely block design (RCBD) with three replications. Disease severity was assessed based on 1-9 scale; 1 being non-pathogenic and 9 being highly pathogenic. The response of common bean genotypes to P. aphanidermatum and P. splendens and their interactions were statistically different (P<0.0001). Two bean genotypes ADP-014 and ADP-080 showed promising trait of resistance, 38 genotypes showed moderate resistant trait and 57 were susceptible to Pythium root rot disease. Keywords: Inoculum, Leguminous, Pathogenic, Resistant trait, Severity.

Integrating Conventional and Participatory Breeding Approaches in Assessment of Common Bean Varieties for Farmer Preffered Traits

Journal of Agricultural Science (2019)

Papias Binagwa Magdalena William Julius Mbiu Eunice Zakayo Shida Mahenge Nestory

It is estimated that over 75% of rural households in Tanzania depend on common bean (Phaseolus vulgaris L.) for daily subsistence. Recently, farmers have been increasingly looking for improved bean varieties which meet specific market demands characterized with yellow seed colour, early maturing and/or adapted to local agro-ecologies. Study focused on assessing the performance of bean varieties for agronomic traits through variety and environmental interactions by identifying high yielding, ealy maturing and market demand seed classes among the tested materials. For testing adaptability and stability, experiments were conducted in low to high altitudes for two consecutive years using randomized complete block design (RCBD) with three replicates. Eight common bean varieties KG98, Navy line 1, KATB9, SABRYT, KATB1, Lyamungu 85, JESCA and Calima Uyole were used. Absolute, matrix and pairwise ranking were used integratively for farmers’ and researcher’s assessment and selection. Participatory variety selection approach gave farmers an opportunity to assess and select varieties from a range of near finished materials in the breeding process. As part of the Farmers’ participatory variety selection process, seventeen participants as among the consumers 46% being women were selected to participate in a focused group discussion. Results revealed that, days to flowering, days to maturity and yield across the tested environments showed significant differences (p ≤ 0.05) as well as yield and diseases interactions for genotype, environment and season. Field data and farmers’ assessment data showed two varieties of KATB1 (yellow round) and KATB9 (red round) for better performance (high yield) and grain preference respectively. It showed that, early maturing; seed type and marketability varieties are highly demanded by bean farmers in Tanzania.

Genome-wide Identification of Powdery Mildew Resistance in Common Bean

Research Square (Research Square) (2020)

Papias Binagwa Sy M. Traore Marceline Egnin Gregory C. Bernard Inocent Ritte

Abstract Background: Genome-wide association studies (GWAS) was utilized to detect genetic variations related to the powdery mildew (PM) resistance and several agronomic traits in common bean. However, its application in common bean and the PM interactions to identify genes and their location in the common bean genome has not been fully addressed. Results: Genome-wide association studies (GWAS) through marker-trait association are useful molecular tools for the identification of disease resistance and other agronomic traits. SNP genotyping with a BeadChip containing 5398 SNPs was used to detect genetic variations related to resistance to PM disease in a panel of 206 genotypes grown under field conditions for two consecutive years. Significant SNPs identified on chromosomes 4 and 10 (Pv04 and Pv10) were repeatable, confirming the reliability of the phenotypic data scored from the genotypes grown in two locations within two years. A cluster of resistance genes was revealed on the chromosome 4 of common bean genome among which CNL and TNL like resistance genes were identified. Furthermore, two resistance genes Phavu_010G1320001g and Phavu_010G136800g were also identified on Pv10; further sequence analysis showed that these genes were homologs to the Arabidopsis disease resistance protein (RLM1A-like) and the putative disease resistance protein ( At4g11170.1 ), respectively. Two LRR receptor-like kinases (RLK) were also identified on Pv11 in samples collected in 2018 only. Many genes encoding auxin-responsive protein, TIFY10A protein, growth-regulating factor 5-like, ubiquitin-like protein, cell wall protein RBR3-like protein related to PM resistance were identified nearby significant SNPs. These results suggested that the resistance to PM pathogen involves a network of many genes constitutively co-expressed and may generate several layers of defense barriers or inducible reactions. Conclusion: Our results provide new insights into common bean and PM interactions, and revealed putative resistance genes as well as their location on common bean genome that could be used for marker-assisted selection, functional genomic study approaches to confirm the role of these putative genes; hence, developing common bean resistance lines to the PM disease.

Impact of botanical extracts on mungbean pest management and seed storability in the northern highlands of Tanzania

Frontiers in Sustainable Food Systems (2024)

Godfrey Adolph Kessy Angela G. Mkindi Papias Binagwa Patrick Alois Ndakidemi

This study assessed the efficacy of plant extracts as alternatives to synthetic pesticides for pest control and seed quality preservation in mungbean cultivation in northern Tanzania, specifically at TARI Selian and Miwaleni. The study employed a randomized complete block design. Four plants’ extracts— Tephrosia vogelii , Clutia abbsynica, Clausena anisata , and Lobelia gibelloa—were evaluated during the 2020 growing season (field) and 2021 storage period (storability). The study focused on their effects on insect pests (leaf beetles, thrips, aphids, whiteflies, and pod borers) and their ability to maintain seed quality during storage. C. anisata emerged as the most effective extract across all pests, demonstrating high suppression rates for thrips (3.4), aphids (3.22), whiteflies (3.4), and pod borers (2.7). In contrast, L. gibelloa was the least effective, with lower suppression rates for thrips (3.1) and aphids (3.1). Furthermore, botanical treatments significantly reduced pest damage in stored seeds, with T. vogelii and C. abbsynica showing superior performance in preserving seed weight and quality during storage. Seeds treated with T. vogelii had significantly fewer holes and lower weight loss compared to other treatments, indicating its effectiveness in both pest management and seed preservation. Conversely, L. gibelloa and C. anisata contributed to greater weight loss, particularly at higher application rates. The study demonstrates that plant extracts can offer a sustainable, eco-friendly alternative to synthetic pesticides, effectively controlling pests and preserving seed quality. These findings are crucial for improving mungbean production and storage, enhancing food security, and reducing reliance on chemical pesticides in diverse agro-ecological contexts. Future research should further explore the long-term ecological impacts and optimal application rates of these botanicals for integrated pest management and seed storage.

Genomics, genetics and breeding of common bean in Africa: A review of tropical legume project

Plant Breeding (2018)

Clare Mukankusi Bodo Raatz Stanley T. Nkalubo Fenta Berhanu Papias Binagwa

Abstract Common bean ( Phaseolus vulgaris L.) is an important legume crop worldwide. The International Centre for Tropical Agriculture ( CIAT ) and its national partners in Africa aim to overcome production constraints of common bean and address the food, nutrition needs and market demands through development of multitrait bean varieties. Breeding is guided by principles of market‐driven approaches to develop client‐demanded varieties. Germplasm accessions from especially two sister species, P. coccineus and P. acutifolius, have been utilized as sources of resistance to major production constraints and interspecific lines deployed. Elucidation of plant mechanisms governing pest and disease resistance, abiotic stress tolerance and grain nutritional quality guides the selection methods used by the breeders. Molecular markers are used to select for resistance to key diseases and insect pests. Efforts have been made to utilize modern genomic tools to increase scale, efficiency, accuracy and speed of breeding. Through gender‐responsive participatory variety selection, market‐demanded varieties have been released in several African countries. These new bean varieties are a key component of sustainable food systems in the tropics.

Adoption of Improved Mungbean Production Technologies in Selected East African Countries

Agriculture (2021)

Frank Mmbando Emmanuel K. Mbeyagala Papias Binagwa Rael Karimi Hellen Opie

This study analyzes the factors that influence the probability and extent of the adoption of mungbean production technologies in Tanzania, Kenya and Uganda, using multivariate probit and Poisson regression models. The results show that the probability and extent of the adoption of mungbean production technologies are influenced by gender of the household, household size, farm size, livestock size, household assets, access to extension services and access to credit. The study suggests that policy interventions that aimed at targeting women farmers, increasing household asset and information dissemination, such as field demonstrations and training programs, are crucial in enhancing technology adoption among smallholder farmers.

Base Editing in Peanut Using CRISPR/nCas9

Frontiers in Genome Editing (2022)

Anjanasree K. Neelakandan Binita Subedi Sy M. Traore Papias Binagwa David A. Wright

Peanut (Arachis hypogaea L.), an allotetraploid legume of the Fabaceae family, is able to thrive in tropical and subtropical regions and is considered as a promising oil seed crop worldwide. Increasing the content of oleic acid has become one of the major goals in peanut breeding because of health benefits such as reduced blood cholesterol level, antioxidant properties and industrial benefits such as longer shelf life. Genomic sequencing of peanut has provided evidence of homeologous AhFAD2A and AhFAD2B genes encoding Fatty Acid Desaturase2 (FAD2), which are responsible for catalyzing the conversion of monounsaturated oleic acid into polyunsaturated linoleic acid. Research studies demonstrate that mutations resulting in a frameshift or stop codon in an FAD2 gene leads to higher oleic acid content in oil. In this study, two expression vectors, pDW3873 and pDW3876, were constructed using Cas9 fused to different deaminases, which were tested as tools to induce point mutations in the promoter and the coding sequences of peanut AhFAD2 genes. Both constructs harbor the single nuclease null variant, nCas9 D10A, to which the PmCDA1 cytosine deaminase was fused to the C-terminal (pDW3873) while rAPOBEC1 deaminase and an uracil glycosylase inhibitor (UGI) were fused to the N-terminal and the C-terminal respectively (pDW3876). Three gRNAs were cloned independently into both constructs and the functionality and efficiency were tested at three target sites in the AhFAD2 genes. Both constructs displayed base editing activity in which cytosine was replaced by thymine or other bases in the targeted editing window. pDW3873 showed higher efficiency compared to pDW3876 suggesting that the former is a better base editor in peanut. This is an important step forward considering introgression of existing mutations into elite varieties can take up to 15 years making this tool a benefit for peanut breeders, farmers, industry and ultimately for consumers.

Market‐led options to scale up legume seeds in developing countries: Experiences from the Tropical Legumes Project

Plant Breeding (2019)

Jean‐Claude Rubyogo Essègbémon Akpo Lucky O. Omoigui Gaur Pooran S. K. Chaturvedi

Abstract There are several hurdles to ensure sustainable seed production and consistent flow of improved legume varieties in sub‐Saharan Africa (SSA) and South Asia (SA). The unreliable demand, autogamous nature of most of the grain legumes, and slow variety replacement rate by smallholder farmers do not provide strong incentive for private seed companies to invest in legume seed business. Unless a well thought‐out and comprehensive approach to legume seed delivery is developed, current seed shortages will continue, eroding emerging market opportunities. The experiences reported here are collated through a 10‐year partnership project, the Tropical Legumes in SSA and SA. It fostered innovative public–private partnerships in joint testing of innovative market‐led seed systems, skills and knowledge enhancement, de‐risking private sector initiatives that introduced in new approaches and previously overlooked entities in technology delivery. As new public and private seed companies, individual seed entrepreneurs and farmer organizations emerged, the existing ones enhanced their capacities. This resulted in significant rise in production, availability and accessibility of various seed grades of newly improved and farmer demanded legume varieties in the target countries.
