GENETIC VARIABILITY AND CHARACTER ASSOCIATION IN CASHEWNUT (ANACARDIUM OCCIDENTALE L.)

Published on

The nature and magnitude of genetic variability and their inter-relationship were studied
for nut yield and its eleven component traits in 17 genotypes of cashewnut (Anacardium
occidentale 1.). High estimates of genotypic coefficients of variation, heritability and
genetic advance were observed for sex ratio, fruit set, number of fruits and apple weight,
indicating their reliability for effecting selections for high nut yield. Fruit set per panicle
and single nut weight were the best contributors to nut yield per plant and further, the nut
weight and apple weight showed high positive association with nut yield both at genotypic
and phenotypic levels. Hence, the studies revealed the importance of nut weight, fruit set
and apple weight as selection criteria for improvement of nut yield in cashewnut.
