Abstract Super Basmati is an elite variety with extra-long grains and superior quality but its yield severely affected by water stress. Recombinant inbred lines (RILs) developed from the cross of IR55419-04 (a coarse grained high potential) were used to identify map yield-related quantitative trait loci (QTLs) under normal field conditions. Genotypes for 244 KASP markers obtained 188 F 9 RILs a...

Premise Whether drought-adaptation mechanisms tend to evolve together, independently, or constrained by genetic architecture is incompletely resolved, particularly for water-relations traits besides gas exchange. We addressed this issue in two subspecies of Clarkia xantiana (Onagraceae), California winter annuals that separated approximately 65,000 years ago and are adapted, partly differences ...

In bread wheat (Triticum aestivum L.), kernel parameters are significant grain quality characteristics that affect yield and milling as well market price. Utilization of synthetic hexaploid donor to harness the diverse alleles for broadening genetic base is a novel breeding strategy programs across globe. An experiment was conducted during winter (rabi) season 2017–18 2018–19 at research farm I...

Kernel weight (KW), together with kernel number per unit area, determines yield of cereal crops. Here, two barley recombinant inbred lines (RILs) populations a shared parent were used to identify loci controlling KW. One is Baudin/AWCS276 (BA) for which linkage map was available. Several large-effect QTL KW detected in this population. Another Morex/AWCS276 (MA). A 5273 makers formed 1454 clust...

Bakanae disease is a fungal of rice (Oryza sativa L.) caused by the pathogen Gibberella fujikuroi (also known as Fusarium fujikuroi). This study was carried out to identify novel quantitative trait loci (QTLs) from an indica variety Zenith. We performed QTL mapping using 180 F2:9 recombinant inbred lines (RILs) derived cross between resistant variety, Zenith, and susceptible Ilpum. A primary ge...

Ecophysiological models predict quantitative traits of one genotype in any environment, whereas quantitative trait locus (QTL) models predict the contribution of alleles to quantitative traits under a limited number of environments. We have combined both approaches by dissecting into effects of QTLs the parameters of a model of maize (Zea mays) leaf elongation rate (LER; H. Ben Haj Salah, F. Ta...

Soybean [Glycine max (L.) Merr] is an important legume crop and its yield largely depends on root architecture (RA) and biological nitrogen fixation (BNF). However, the relationship between RA and BNF, and its genetics behind remain unclear. Here, two soybean genotypes contrasting in RA and their 175 F9:11 recombinant inbred lines (RILs) were evaluated in field. The shallow-root parent, JD12, h...

Seed weight and seed size both are quantitative traits and have been considered as important components of grain yield, thus identification of quantitative trait loci (QTL) for seed traits in lentil (Lens culinaris) would be beneficial for the improvement of grain yield. Hence the main objective of this study was to identify QTLs for seed traits using an intraspecific mapping population derived...

Quantitative trait loci (QTL) mapping is a powerful tool for investigating the genetic basis of natural variation. QTL can be mapped using a number of different population designs, but recombinant inbred lines (RILs) are among the most effective. Unfortunately, homozygous RIL populations are time consuming to construct, typically requiring at least six generations of selfing starting from a het...
