Canonical variate analysis in pigeonpea [Cajanus cajan (L.) Millsp.].

摘要

Fifty entries were raised in randomized block design and canonical variate analysis was done in an experiment conducted in Tamil Nadu, India. The first three principal components indicated that the characters, plant height, number of branches, pods per plant and 100-seed weight have contributed more towards discrimination of the entries. Twenty-four clusters were formed and in those 14 were solitary clusters. D2 analysis was also done to confirm the genetic diversity. The entries ICPL 88034 and ICPL 88039 were found to be closely related and the entries ICPL 86015 and SPMA 6 were distantly related. There is no parallelism between genetic and geographic diversity.
