Abstract
A study was carried out to assess the genetic architecture of 36 genotypes of satputia. Fruit yield and fourteen yield contributing traits
were recorded from five plants at random. The mean performances of 36 satputia genotypes for yield and its attributing traits showed
wide variation. The difference between the genotypic and phenotypic correlation coefficients was narrow for various traits. This
indicates lesser influence of the environment in the expression of these traits and the presence of a strong inherent association among the traits. High heritability (%) estimates coupled with high genetic gain (%) were observed for fruit yield per plant (88.27, 72.08), number of fruits per plant (87.83, 53.60), average fruit weight (87.17, 45.41), number of primary branches (91.25, 46.73) and fruit diameter (79.15, 43.13), indicated that these traits are under additive gene effects, hence are more reliable for effective selection. The highest positive significant direct effect on yield was recorded by fruit length, followed by number of clusters per plant, node number of the first hermaphrodite flower and number of fruits/plant at both genotypic and phenotypic levels. Therefore, direct selection for these traits would be worthwhile for the improvement of yield in satputia.
