GENOTYPIC PERFORMANCE OF PRESOWN SUGARCANE UNDER SOUTHERN PUNJAB CONDITIONS

Abstract

The studies on the relative production potential of ten sugarcane clones were carried out at sugarcane research station, Khanpur during the year 2012 under hot dry conditions of Southern Punjab. The varieties included in the trail were S2006SP.18, S2006SP.25, S2006SP.30, S2006US.321, S2006US.469, S2006US.640, S2006US.641, S2006US.658, S2006US.832 and CPF.247 (Check).The new promising sugarcane variety S2006US.658 with better germination (53.55%), average tillering (1.50 per plant), good 100-cane weight (101.67 Kg), the highest millable cane count (107.04 thousand per hectare), maximum cane yield (108.70 t/ha) and better CCS (12.50%) superseded the tested clones in sugar production (13.58 t/ha). It was followed by the check variety CPF.247.Hence the new variety S2006US.658 with 5.76 and 6.01 % more cane and sugar yield, respectively over control is capable of replacing the check variety. A wide scale testing in various agroecological zones is however invited for regional adoptability.
