Heterosis and combining ability studies under artificial epiphytotic condition for yield and its related traits in Indian mustard

Journal of Oilseeds Research (2023)

DIVYA PRAKASH B. Sinha Kartikeya Srivastava

The performance of Indian mustard genotypes for eleven morpho-physiological traits was assessed. Genotypes (lines) having white rust resistance viz., BioYSR, Donskaja, Heera and Basanti, were crossed with genotypes (testers) having high per se performance for yield viz., Varuna, Kranti, RH749 and Giriraj in the line × tester fashion. The analysis of variance revealed significant mean sum of squares due to crosses for all traits. All traits, except area under disease progression curve and daysto 50% flowering, showed both, additive and a predominance of non-additive gene action. Results suggested that heterosis breeding would lead to good result. All traits had lower levels of narrow sense heritability, as well. Predominance of non-additive gene action coupled with low heritability suggested that, selection should be practised once plant reach sufficient levels of homozygosity. Single seed descent method with large F2 and diallel selective mating design would be preferable for obtaining superior pure lines. Additionally, all lines showed significant desirable general combining ability for disease resistance. Varuna × BioYSR was the only cross that showed significant heterosis for yield over national check, Kranti. It also revealed significant heterobeltiosis for: seeds per siliqua, number of primary branches, days to 50% flowering, AUDPC and days to maturity. This potential hybrid can be deployed with the help of cytoplasmic-genetic male sterility, or it can be utilised to obtain superior purelines through conventional breeding methods.

Molecular diversity analysis of Asparagus racemosus and its adulterants using random amplified polymorphic DNA (RAPD)

Journal of Medicinal Plants Research (2013)

Akansha Singh Ved Prakash Major Singh Amit Kumar Singh B. Sinha

Leaves of 28 genotypes of 4 species of the genus Asparagus, namely: Asparagus racemosus, Asparagus falcatus, Asparagus officinalis and Asparagus plumosus were analyzed for genetic diversity by random amplified polymorphic DNA (RAPD). Out of one hundred 10-mer RAPD primers screened, 25 were selected for comparative analysis of different accessions of A. racemosus and its closely related species. High genetic variations were found between the different Asparagus species studied. Among a total of 296 RAPD fragments amplified, 287 bands (96.95%) were found polymorphic in the four species. Average polymorphic information content (PIC) value for the amplification product was 0.23. Fourteen species-specific bands were found in A. racemosus species. These species-specific RAPD markers could potentially be used for identifying authentic A. racemosus spp. and could be sequenced for conversion to a sequence-characterized amplified region (SCAR) marker so as to serve as species specific marker. Jaccard’s genetic similarity co-efficient varied from 0.19 to 0.85. The unweighted pair group method with arithmetic average (UPGMA) dendrogram was constructed on the basis of Jaccard’s genetic similarity co-efficient values that separate the three other species of Asparagusfrom A. racemosus accessions. Results of this study will facilitate authentic A. racemosusidentification, thereby aiding drug standardization, its collection, management and conservation. Key words: Medicinal herb, genetic diversity, molecular marker, authentication, conservation.

Microbiological resources- an alternate approach for sustainable management of fall armyworm (Spodoptera frugiperda)

Journal of Agriculture and Ecology (2023)

B. Sinha Haldhar SM K. Chakrapani CN Nidhi Zonunkimi Ralte

Fall Army Worm (Spodoptera frugiperda), with the traits of devastating, voracious, polyphagous nature had recently imposed a global threat. Possessing these traits, this pest constituted a threat to global food security by ambushing more than several host plant species. To tackle this pest, insecticide management approaches was used initially. Later, with a better comprehension of the dynamic biology of the pest, such as their long migration capability, their ability to develop resistance against insecticide and the adverse effects of pesticides on human and the environment, an alternative strategy which is environmentally safe i.e., biological control approaches that is effective and low-risk is laid emphasis. A rich diversity of microbial populations which have the ability to infect the pest to a certain degree in nature remains untapped, and if so, identification of high virulence and productive strains within the population is lacking hitherto. This review focused on the information regarding the scenario of the occurring pest and its damaging nature to the host plants and microbial agents with their surplus potentialities along with the mode of interactions with the insect pest and self-perpetuating nature and their boon of disarming nature. The details of each microbe viz., fungi, bacteria and viruses that possess the traits of controlling the pest naturally are briefed with an insight into molecular information, present findings, constraint and future prospects.

Identification of transcription factors in tomato, potentially related to early blight resistance at invasion in host tissue, using microarray expression profiling

South African Journal of Botany (2016)

Priti Upadhyay Showkat Hussain Ganie Ashutosh Rai Major Singh B. Sinha

Tomato early blight is an important threat due to its capacity to reduce the production in all major tomato producing areas. Molecular mechanisms underlying resistance to the causal organism are not well known. Therefore, we aimed to study tomato – Alternaria solani system to search the transcription factors and pathways which, are responsible for resistance to this fungi using, affymetrix gene chip for tomato. three hundred ninety five transcription factors were found to be differentially expressed at 24 h after inoculation with A. solani in the resistant genotype, EC-520,061, of tomato. Also, Zinc Finger Proteins, Ribosomal binding unit S4 and Auxin responsive transcription factors were found to play significant role in resistance. Their expression has enhanced the pathogenesis related proteins and also other proteins as well, which, have direct role in stopping the penetration of mycelia in host plant. • This study is an attempt to understand the regulatory network of transcription factors which play role in resistance response in tomato under stress of early blight pathogen ( A. solani ). • At the very initial stage, i.e. penetration of host tissue by fungal mycelium (24 hai), the samples were collected and transcriptome profiling was done using Affymetrix Gene Chip and it has shown differential expression of different transcription factors. Also these have been compared with previous studies and found that these TFs are important in regulatory network of resistance pathways.

Journal of the Indian Society of Soil Science (1964)

S. C. Agarwala N. K. Mehrotra B. Sinha

A study was made of the effect of E.S.P. on the growth and mineral composition of barley plants grown in soils of sodium carbonate and bicarbonate series, each at nine E.S.P. and of paddy plants grown in soils of sodium carbonate, bicarbonate and sulphate series, each at thirteen E.S.P. Growth of barley and paddy plants was depressed at high E.S.P. on soils of sodium carbonate and bicarbonate series. In the sodium sulphate series, there was hardly any growth depression in paddy.

Study of Ppd-D1 gene impact on different phenotypic traits in wheat (Triticum aestivum L.)

Journal of Pharmacognosy and Phytochemistry (2019)

Pargat Singh VK Mishra B. Sinha Shweta Singh

Wheat is world’s most widely cultivated food crop after rice which belongs to the family Graminae (Poaceae) and the genus Triticum. Presence and level of expression of Ppd genes in winter wheat and spring wheat varieties can be photoperiod sensitive or insensitive. The photoperiod insensitive wheat varieties are early to flowering in short days condition as compared to their counterpart photoperiod sensitive varieties. Photoperiod sensitivity is controlled by Ppd-A1, Ppd-B1 and Ppd-D1 genes of group 2 chromosomes. Ppd-D1 gene has been identified as the major source of earliness in wheat varieties worldwide. All the 242 lines of wheat were genotyped with Ppd-D1 marker and observed 1:1 segregation among the population for the presence and absence of this gene. It was observed that presence of this gene reduced 11 traits as compared with those lines which had no Ppd-D1 gene but few traits were expressed positively by the presence of this gene. Reduction in days to heading and plant height is the common effect observed by many researchers and days to heading also affect the spot blotch severity as reflected by area under disease in this experiment. Diversity in climate is attribute of India and variability created by Ppd-D1 gene for flowering time may be exploited in breeding programme for development of varieties for divergent regions.
