Genetic variability in nine cultivars of coconut (Cocos nucifera L.)

Abstract

An experiment conducted at the Instructional Farm, College of Horticulture, Vellanikkara, Thrissur on nine coconut cultivars during 1995-96 in RED with three replications and three palms per plot revealed the absence of significant variation among most of the characters. Economic characters showed higher genotypic coefficients of variation (16 to 22 %) compared to vegetative and reproductive characters. Among all the characters, hcritability was maximum for petiole length (52 %) followed by the economic characters, per cent oil content and nut yield (45% each).
