Phenotypic evaluation of a set of selected exotic maize inbred lines for drought stress tolerance

Indian Journal of Genetics and Plant Breeding (The) (2010)

L. N. Dubey B. M. Prasanna Firoz Hossain Damini Verma B. Ramesh

Increased rainfall variability accentuated by climate change will have severe effects on production of maize which is grown predominantly as a rainfed crop in India. A set of 31 exotic inbred lines were analysed under both well-watered (controlled) and water-deficit stress (at flowering stage) conditions at the IARI Experimental Farm, New Delhi (during Kharif 2007), and IARI Regional Station, Pusa-Bihar (during Rabi 2007–08). Significant variation among the genotypes were observed for grain yield per plant, anthesis-silking interval (ASI), number of ears per plot, total number of leaves per plant and leaf senescence, under both well-watered and drought-stressed conditions. Significant effects of locations/seasons and environments, besides location/season × genotype and environment × genotype interactions for most of the drought component traits were analysed. The study led to the identification of a few inbreds, such as DTPYC9-F46-1-2-1-2-B, CML341, CML340 and CMLP2 at Delhi, and CML340, LPSC7-F64-2-6-2-2-B-B, LPSC7-F71-1-2-1-1-B-B, CMl360 and CML341 at Pusa (Bihar) as promising drought-tolerant genotypes.The study also established the negative association of ASI with ear per plot as well as with grain yield per plant under water stress conditions at both the locations. Leaf senescence was also found to be negatively correlated with ear per plot and grain yield per plant, thereby confirming the usefulness of lower ASI and leaf senescence as the potential secondary traits for breeding under drought stress conditions in rainfed maize.

Genetic variability of popping quality traits and microsatellite-based characterization of popcorn inbreds for utilization in breeding programme

Indian Journal of Genetics and Plant Breeding (The) (2020)

Deepa Pal Vignesh Muthusamy Rajkumar U. Zunjare Sunil K. Jaiswal Rashmi Chhabra

Popcorn is a popular snack item worldwide. The genetic base of popcorn germplasm is quite narrow, which resulted in limited number of popcorn hybrids. Here, a set of sub-tropically adapted 39 popcorn inbreds of exotic- and indigenous-origin, were characterized using morphological traits and molecular markers for their effective utilization in hybrid breeding. Significant variation for grain popping percentage (GPP: 86.0-98.0%), percent popping expansion (PPE: 1493-3213%) and volume after popping (VAP: 210-315ml) was observed. The mean PPE (2069%) and GPP (93.6%) among popcorn inbreds were higher than the popcorn check variety, VL popcorn (PPE: 1739%, GPP: 92%). Positive correlations were observed among GPP, PPE and VAP. Molecular characterization using 72 SSRs produced 237 alleles with a mean of 3.3 alleles per locus. Polymorphism information content ranged from 0.05 to 0.68, while Jaccard’s dissimilarity coefficients varied from 0.27-0.82. Principal coordinate analysis also depicted diverse genetic nature of inbreds. Cluster analysis grouped the inbreds into three major clusters each having 16, 18 and 5 inbreds. Contrasting inbreds were identified for development of mapping populations to identify loci governing desirable popping quality. The study also identified potential heterotic combinations. The information generated here assumes great significance in breeding for popcorn hybrids.

Incorporation ofopaque-2into ‘UMI 1200’, an elite maize inbred line, through marker-assisted backcross breeding

Biotechnology & Biotechnological Equipment (2019)

Bharathi Pukalenthy Manickam Dhasarathan Sarankumar Chandran Adhimoolam Karthikeyan S. Vellaikumar

Maize is an important agricultural plant valued for its productivity and nutritive qualities. However, a deficiency of two essential amino acids (lysine and tryptophan) significantly reduces the nutritional quality of maize proteins. The recessive opaque-2 (o2) mutant has a greater content of lysine and tryptophan in their endosperm proteins and their bioavailability is better. Therefore, marker-assisted backcross breeding (MABB) was attempted to incorporate the o2 allele from the donor line VQL 1 into the genetic background of UMI 1200 to develop quality protein maize (QPM) lines. Foreground selection for the gene o2 was effected using tightly linked molecular marker umc1066, in UMI 1200 × VQL 1 backcross series. Further, background selection was done together with stringent phenotypic selection for agronomic traits, to accelerate recurrent parent phenome recovery. As a result, three advanced QPM maize lines (DBT 4-1-1/25-10/25-10/25-16, DBT 4-1-1/25-10/25-17/25-11 and DBT 4-1-1/25-10/25-17/25-13) carrying the opaque-2 allele in a homozygous state, similar to VQL 1 were developed. The lysine and tryptophan content of these lines ranged from 0.35% to 0.40% and 0.03 to 0.05%, respectively, which is on par with the VQL 1. Background analysis using 250 simple sequence repeats (SSRs) revealed up to 97% recurrent parent genome recovery. In conclusion, the newly developed QPM lines can be used in future maize breeding programmes to improve the nutritional traits.

Investigation on comparative transcriptome profiling of resistant and susceptible non-CMS maize genotypes during Bipolaris maydis race O infection

Heliyon (2024)

Maydis leaf blight is a significant disease of maize caused by Bipolaris maydis race T, O and C. Molecular mechanisms regulating defense responses in non-CMS maize towards race O fungus are not fully known. In the present investigation, comparative transcriptome profiling was conducted on a highly resistant maize genotype SC-7-2-1-2-6-1 against a standard susceptible variety CM 119 at 48 h post inoculation (h PI) along with non-infected control. mRNA sequencing generated 38.4 Gb data, where 9349602 reads were mapped uniquely in SC-7, whereas 2714725 reads were mapped uniquely in CM-119. In inoculated SC-7, the total number of differentially expressed genes (DEGs) against control was 1413, where 1011 were up-regulated, and 402 were down-regulated. In susceptible inoculated genotype CM 119, the number of DEGs against control was 2902, where 1703 were up-, and 1199 were down-regulated. DEGs between inoculated resistant and susceptible genotypes were 10745, where 5343 were up-, and 5402 were down-regulated. The RNA-seq data were validated using RT-qPCR. The key findings are that SC-7 poses a robust plant signaling system mainly induced by oxidation–reduction process and calcium-mediated signaling. It regulates its fitness-related genes efficiently, viz., aldolase 2 gene, isopropanoid, phyto hormones, P450 cytochrome, amino acid synthesis, nitrogen assimilation genes etc. These findings showed more transcriptional changes in the SC-7 genotype, which contains many defence-related genes. They can be explored in future crop development programmes to combat multiple maize diseases. The current finding provides information to elucidate molecular and cellular processes occurring in maize during B. maydis race O infection.
