Studies on genetic variability parameters for yield and its component traits in advance hybrid clones of sugarcane

Abstract:
The present investigation was undertaken to estimate the genetic parameters on 14 quantitative traits of 35 clones selected from clonal-I population derived from a cross Co 7204 x Co Pant 97222 and 7 commercial sugarcane genotypes. Analysis of variance showed significant differences among the clones for all the characters studied, indicating the presence of a considerable amount of variability in the genetic material. The transgressive segregants viz., SNK13101 and SNK13142 exhibited significantly superior cane and sugar yield over both the parents, with better potential compared to Co86032. These clones could be advanced for detailed yield trails for potential identification as parents and/or commercial clones in future. The estimates of GCV, PCV, heritability (broad sense) and genetic advance as percent of mean were recorded high for cane yield, commercial cane sugar yield, number of millable cane, brix yield and green top yield indicating that simple selection would be helpful for the improvement of these traits as these are governed by additive gene action whereas cane height recorded moderate heritability along with genetic advance suggesting that characters are governed by both additive and non-additive gene action.
