The appropriate timing of developmental transitions is critical for adapting many crops to their local climatic conditions. Therefore, understanding the genetic basis of different aspects of phenology could be useful in highlighting mechanisms underpinning adaptation, with implications in breeding for climate change. For bread wheat (Triticum aestivum), the transition from vegetative to reprodu...

The research was undertaken during June-October 2020 at Seethanagaram and Draksharam villages of East Godavari district, Andhra Pradesh, India with an objective to evaluate efficiency genomic selection models involving 1545 recombinant inbred lines (RILs) derived from eleven bi-parental populations in Rice. During 2020, the F7 RILs were screened two hot spot locations. genotyping done Infinium ...

Recombinant inbred lines (RILs) are a valuable resource for building genetic linkage maps. The presence of genetic variability in the RILs is essential for detecting associations between molecular markers and loci controlling agronomic traits of interest. The main goal of this study was to quantify the genetic diversity of a common bean RIL population derived from a cross between Rudá (Mesoamer...

Individual grain weight is a major yield component in wheat. To provide a comprehensive understanding of grain weight determination, the carpel size at anthesis, grain dry matter accumulation, grain water uptake and loss, grain morphological expansion, and final grain weight at different positions within spikelets were investigated in a recombinant inbred line mapping population of bread wheat ...

The seed proteome of two traditional maize inbred lines (pb269 and pb369) contrasting in grain hardness and in preferable use for bread-making was evaluated. The pb269 seeds, of flint type (i.e., hard endosperm), are preferably used by manufacturers, while pb369 (dent, soft endosperm) is rejected. The hypothesis that the content and relative amounts of specific proteins in the maize flour are r...

Spanish bunch groundnut varieties occupy most of the cultivated area in Asia and Africa, these lack required 2-3 weeks fresh seed dormancy (FSD) hampering kernel quality. Genomic breeding can help to improve commercial cultivars for FSD a shorter time with greater precision. In this regard, recombinant inbred line (RIL) population from cross ICGV 02266 (non-dormant) × 97045 (dormant) was develo...

Four sets of recombinant inbred lines of mice have been used to analyze genetic differences in acute toxicity of the drug, isonicotinic acid hydrazide. Standard inbred strains, their F(1) hybrids and recombinant inbred strains were all challenged with a single dose of the drug. The percent mortality of the different groups was analyzed to estimate heritability and the number of genes affecting ...

Wheat is one of the most important crops in world. Mapping QTLs for root traits essential selection wheat roots desirable efficient acquisition nutrients. Here, a QTL analysis was performed using 142 recombinant inbred lines derived from two varieties Xiaoyan 54 and Jing 411 soil column culture trial. The genetic map used this study contained 470 SSR markers covered 3438.4 cM genome. A total 25...

Abstract Pre-harvest sprouting (PHS) induced by the absence of seed dormancy causes a severe reduction in crop yield and flour quality. In this study, we isolated characterized TaABI4 , an ABA-responsive transcription factor that participates regulating germination wheat. Sequence analysis revealed has three homologues, located on chromosomes 1A/1B/1D. contains conserved AP2 domain, AP2-associa...
