All traits showed higher values of phenotypic
coefficient of variance than genotypic coefficient of
variance (Table 1). While studying broad sense
heritability it is depicted that high estimates are
present for all traits like plant height (98%),
CLCuV% (96.8%), nodes to first fruiting branch
(95%), bolls per plant (91.5%), sympodia per plant
(88.8%), yield (88%) monopodia per plant (84.7%)
and for boll weight (82.3%). Analysis of variance
revealed that significant differences are present
among all genotypes for all traits studied (Table 1).
The results of GCV and PCV, and heritability are
given in Table 1.
