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 with seven sugarcane genotypes for cane yield (t/ha), CCS (t/ha), CCS % juice, brix (%), sucrose (%) and single cane weight (kg) at maturity stage (300 Days) on three year data viz; 2010-11 to 2012-13. Based on the linear component (bi), non-linear response (s2di) and high mean performance (X) the genotypeCoH07261 and Co 06032 were found stable for cane yield (t/ha) and CCS yield(t/ha), whereas Co 07025 was found stable for CCS % juice,brix %,sucrose % and single cane weight (kg.) and high sustainability index of more than 90 % indicated that these traits are least influenced by the environmental factors.
