PHENOTYPIC STABILITY FOR CANE YIELD IN SUGARCANE

Abstract

Thirteen varieties of sugarcane including four released varieties (Co 1148, Co 1158, Co 7717 and Co 7314) were investigated for G x E interaction for cane yield during three successive years (1979 through 1982). The mean squares due to geno- type, environment and G x E interaction were found highly significant. Co 7314 was the highest yielder in each year. On the basis of regression coefficient and deviation from regression, Co 1148 was found the most desirable variety. This variety was also second highest cans yielder over the years.
