Study of Genetic Variability among Midlate Maturing Sugarcane Clones for Different Yield and Juice Quality Traits under Waterlogged Condition
International Journal of Current Microbiology and Applied Sciences
Genetic variability for twenty five traits were studied in sixteen phenotypically diverse midlate maturing sugarcane clones, which were planted in RBD in three replications at Dr. R.P.C.A.U. Research Farm Pusa Bihar during spring season 2016-2017. The study revealed highly significant differences among all clones for all yield attributing and juice quality traits, indicated the ample variation. The magnitude of genotypic and phenotypic coefficient of variation for yield attributing traits were
... ound moderate for germination percentage at 45 DAP, number of shoot at 120 DAP (000/ha), number of millible cane at harvest (000/ha), cane yield (t/ha), sugar yield (CCS t/ha), plant height at 150 DAP, leaf area index before waterlogging, leaf area index at 30 days after waterlogging, leaf area index at 60 days after waterlogging, number of fully emerged leaves at 30 days after waterlogged and number of fully emerged leaves at 60 days after waterlogged. The numerical value of phenotypic variation was higher than their genotypic counterpart for all the characters. The result of present study clearly indicated the importance of traits such as sugar yield (CCS t/ha), cane yield (t/ha), leaf area index before waterlogging, leaf area index at 30 and 60 days after waterlogging as they exerted high genetic advance as percentage of mean coupled with high heritability. These traits were controlled by additive gene action; hence, phenotypic selection could be effective in improvement of such traits.
