Abstract
Evaluation and identification of varieties for different agro-climatic condition is of prime importance in sugarcane cultivation for farmers. The present investigation was undertaken with the objective of evaluation of sugarcane clones for yield and quality and its contributing traits. The Experimental materials consist of five test clones viz., CoA 13322, CoA 13323, CoC 13336, CoC 13337 and CoV 13356 and two standard checks (CoC 01061 and CoA 92081). Observations were recorded for germination per cent (%), number of tillers (x1000/ha), number of millable cane (x1000/ha), cane length (cm), Cane diameter (cm), Single cane weight (kg), cane yield (t/ha), brix (%), Purity (%), sucrose (%), CCS (%) and CCS yield (t/ha). Based on the results of the different clones for different traits evaluated, the clone CoC 13336 was found the best performing clone in respect of cane yield (140.71 t/ha), CCS yield (18.23 t/ha) and other important traits over the standards (checks). The clone CoC 13337 was the next best performing clone for cane yield (139.92 t/ha), CCS yield (17.93 t/ha) and other traits over the standards and these two clones may be promoted for further evaluation trial for the release new sugarcane variety suitable for early season of Tamil Nadu.
