Analysis of combining ability on production related traits in several new indica sterile line
Abstract：Through NCⅡ incomplete dialle crossing design,using 6 new indica sterile lines and 5 early maturing restores lines,combining ability and heritability of 11 production related traits of hybrid F1 were analyzed.The results showed that the differences of general combining ability and specific combining ability of most traits reached a significant level or extremely significant level.The contribution of restorer line and sterile line to the genotypic differences of general combining ability was different due to the different characters.Narrow heritability of different traits was ear lengthfilled grain number per panicleplant heighteffective panicleseed setting rateyield per plantrelative daily outputgrain number per paniclewhole growth periodgrain density1000-grain weight.It was easy to got dominance cross combinations by using the sterile lines Quan5A and LA2012.
