The main emphasis of wheat breeders is to strive for genetically more stable, high yielding varieties than the pre-released ones to sustain the yield. Yield improvement efforts should be made while considering all contributing factors that can improve it. The role of peduncle length influencing yield and other supporting features are barely taken into consideration, and still not fully elucidated. Understanding and utilization of plant natural response will help to develop genetically and morphologically more adaptable genotypes for ever-increasing feed demand. The present research was conducted to assess the nature of gene action controlling inheritance of these traits coupled with manipulating role for yield traits. In this regard, 27 F1 hybrids were developed by crossing 9 female and 3 male parents using Line × Tester (L×T) mating design and evaluated for yield and its related traits. The analysis of variance for combining ability pointed out the presence of broad genetic variation in material with highly heritable nature. Correlation studies portrayed strong phenotypic and genotypic association between peduncle length, plant height, flag leaf area, spike length and grain weight/plant. Strong association of peduncle length with other yield contributing traits may be utilized as an indirect selection criterion for yield improvement. Hence, short stature and high yielding varieties can be developed by controlling the favourable genes for peduncle length. All yield related traits except peduncle length, spike length, and flag leaf area were controlled by dominant genes. Selection in the later generations for peduncle length may indirectly improve yield.
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.
