Association analysis in sugarcane (Saccharum officinarum L.)

Abstract

Correlation studies among ten characters were studied in twenty genotypes of sugarcane (sugarcane varieties, species and related genera). In general, genotypic correlation coefficients were higher than the corresponding phenotyic correlation coefficients suggesting that the environmnetal influence reduces the relationship between cane yield per plot and its contributing characters and sugar yield per plot and its contributing characters in sugarcane. The cane yield per plot showed significant positive correlation with cane thickness, single cane weight, brix per cent, sucrose per cent and commercial cane sugar per cent. The sugar yield per plot showed significant positive correlation with cane yield per plot and its contributing characters (5) mentioned above
