Genetic Variability of Different Morphological and Yield Contributing Traits in Different Accession of Saccharum Officinarum L

Abstract

Ten genotypes of sugarcane (Saccharum officinarum L.) viz. COJ-84, CPF-235, COL-54, SPSG-26, COJ-64, SPF-232, CPF-237, S-97-US-297, KATHA and No-61 were evaluated for twelve characters and analyzed for genotypic and phenotypic correlation. Analysis of variance indicated highly significant differences exist for all the traits. Among the traits leaf area, number of tillers, cane thickness, and cane yield had the positive and significant correlation with brix value at both genotypic and phenotypic levels. Cane height had negative but non-significant correlation with brix value at genotypic and phenotypic level. Similarly cane weight had positive correlation both at genotypic and phenotypic level with cane height, number of tillers per plant and brix value. The study of path analysis for yield related traits depicted that cane height, cane thickness, leaf area, internodal length and brix value had the direct negative effects on yield.
