Abstract:
Thirty early maturing sugarcane clones were planted in a randomized block design during 2018-19 at ARS, perumallapalle, Tirupathi, Andhra Pradesh to study the variability in cane yield and its component traits. The characters studied were germination count at 30 DAP, tillers at 90 DAP, tillers at 120 DAP, shots at 240 DAP, NMC ('000/ha), cane length, cane diameter (cm), single cane weight (kg), number of nodes per cane, fibre per cent, Brix, sucrose, purity, CCS % at 8th and 10th months, cane yield and CCS yield (t/ha) at harvest. Analysis of variance revealed that significant differences observed for all the traits among the clones. The PCV is greater than GCV for most of the traits under study. The characters such as number of nodes per cane, cane length, CCS yield and cane yield showed high heritability coupled with high GAM indicates that presence of additive gene action and selection is effective for these traits. Hence these traits can be utilized for further selection and genetic improvement of early maturing clones.
