Heritability and Genetic Variance Components in Sunflower Single Cross Hybrids

Abstract

In order to estimate genetic parameters in 16 Sunflower single cross hybrids obtained from crossing of 4 cytoplasmic male sterile and 4 fertility restorer lines, a North Carolina Design II was conducted using RCBD design with 3 replications at Khoy Agriculture Research Station. The result of this experiment indicated that gene action for plant height, seed number per head, first leaf area, grain yield, harvest index of head and seed weight per head was over dominant (a>1), and in other traits was partial dominant (a
