Studies on stability parameter and sustainability index for selecting stable genotypes of sugarcane (Saccharum officinarum L.)
Abstract
A comparative studies on stability parameters and sustainability index for selecting stable genotypes of sugarcane was carried out according to Eberhart and Russell Model, with sustainability index model. Stability analysis was carried out on seven sugarcane genotypes for cane yield (q/ha), CCS (q/ha), CCS % juice, Brix (%), Sucrose (%) and single cane weight (kg) at maturity stage (300 Days) on three year data viz; 2010-11,2011-12 and 2012-13. Based on the linear component (bi), non-linear response (s2di) and high mean performance (X) the genotype CoH-7261 and Co-6032 were found stable for cane yield (q/ha) and CCS q/ha yield, whereas genotype Co-7025 was found stable for CCS % juice, Brix %, Sucrose % and Single cane weight (Kg.) and on the basis of high sustainability index more than 90 % which indicated that these traits are least influenced by the environmental factors.
