To estimate heritability and association between traits traits, recombinant inbred lines and their parents (Yecora Rojo and No.) were evaluated in Alfa lattice design with two replications under normal and water deficit conditions during two cropping season (-). Results showed that there were significant differences between genotypes for all studied traits. The estimated heritabilities for spikes per square meter, stem weight, biomass, spike length, peduncle length, peduncle weight, shoot length, number of grains per spike and spike weight were in the range of. to. and for grain yield,-kernel weight and harvest index were in the range of. to. , respectively. Under water deficit conditions, estimated heritabilities for spike length, spike weight, shoot length, spike per square meter, biomass, peduncle weight, peduncle length and stem weight were between. to. percent and for number of grains per spike, harvest index, thousand kernel weight and grain yield were in the range of to. percent. The highest genetic gain in both conditions belongs to peduncle weight and harvest index, respectively. Finally based on regression and path analysis traits of number of grains per spike and-kernel weights were identified as the most effective traits on grain yield in both conditions. Therefore, use of harvest index, grain yield, number of grains per spike and grain weight as indicators of selection, probably can provides access to highyielding lines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
