| description | The field experiment comprised of 30 cowpea genotypes were evaluated for genetic variability for important
quantitative and quality traits during the Summer 2019 season. Analysis of variance showed that there was significant
differences among the genotypes evaluated for all the characters studied. A high value of phenotypic coefficient of
variation than genotypic coefficient of variation was observed for all the characters which revealed the influence of
environment for phenotypic expression of the traits. High heritability and the high genetic advance were observed for
days to 50% flowering, leaf width, the number of nodes on main stem, the number of main branches, the number of
pods per plant, length of pod, the number of seeds per pod, test weight, seed yield per plant, fat content, lignin content
and host preference mechanism of pulse beetle on the grain of cowpea indicating that the characters are governed
by additive gene action and the characters which can be improved by simple selection. On Mahalanobis D2 statistics,
the genotypes were grouped into four clusters. A maximum number of genotypes was observed in cluster I with 16
genotypes followed by clusters II and III with 8 genotypes each and cluster IV with solitary genotype. On the basis of
divergence classes studied the genotypes viz., PMCP-1021, CP-20, CP-25, CP-26, CP-7, CP-2-1, CP-15, CP-9-1,
CP-17, CP-2-1, PCP-1809, PCP-1124, PCP-1123, Phule Rukmini and Phule Pandhari can be used for the further
breeding programme. |
