Variability studies and frequency distribution for yield and juice quality traits of sugarcane ratoon under water logged situation
Author(s): Dr. Balwant Kumar
Abstract: In an experiment, ratoon of sixteen sugarcane clones including two checks were evaluated during 2013-14under low land area where its grand growth phase coincides with water stagnation depth 40-45 cm for three months at Paddy Block, RPCAU Pusa Farm, Samastipur, Bihar to study the variability and frequency distribution for yield and juice quality traits. Wide ranges of the frequency distribution and highly significant variations amongst ratoon of 16 clones were found for the traits viz, number of Shoots at 120 days, plant height at 150, 240, and at harvest, cane diameter at harvest, NMC at harvest, single cane weight at harvest, brix % at 9 & 11 month, pol % in juice at 9 & 11 month, purity % at 9 & 11 month, CCS percent at 11 month, cane yield at harvest and CCS t/ha at harvest. The phenotypic variances for all the traits were exhibited higher than the genotypic variances due to major role of non-genetic factors. High values of phenotypic and genotypic coefficient of variation coupled with high heritability and high genetic advance percentage as mean were observed for the traits viz, CCS t/ha at harvest, cane yield at harvest, plant height at 240 days and number of shoots at 120 days. Moderate values of PCV and GCV along with high heritability and high genetic advance percentage as mean were recorded for the traits viz plant height at harvest, single cane weight NMC and plant height at 150 days. High heritability coupled with high genetic advance percentage as mean showed by the traits namely, CCS t/ha, plant height at 240 days, cane yield, number of shoot at 120 days, plant height at harvest, cane diameter, single cane weight, plant height at 150 days and NMC indicating role of dominant genetic effect in determining of these traits therefore, all these nine traits can be used for further sugarcane improvement of ratoon crops under water logging condition.
