Genetic variation in maize inbred lines under temperate conditions
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Present study was carried out to generate information on gene action using Hayman’s component of diallel analysis. The experimental material comprised 30 crosses which were generated by crossing between six maize inbred lines in a diallel mating design during Kharif 2014. These 30 crosses along with standard checks viz., Vivek Hybrid-45 and SMC-7 were evaluated in randomized block design in three replications during Kharif 2015 and Kharif 2016. Significant variation was observed for all studied traits during both the seasons. Both additive (D) and dominance (H1 and H2) components of genetic variance were found significant under the study. Preponderance of non-additive gene action was observed for all traits under study. Average degree of dominance was in over dominance range for all characters. The gene distribution was asymmetrical for all traits. The value of KD / KR indicated presence of excess of dominant genes for all traits except 100 grain weight and ear girth. Heritability of most of the traits was low to medium.
