Morphological diversity study in horsegram (Macrotyloma uniflorum (Lam.) Verdc) based on Principal Component Analysis (PCA)
Horsegram is an important arid legume known to grow in the tropical countries of Asia and Africa. A total of 500 accessions from NBPGR regional center, Thrissur and landraces maintained in AICRP on arid legumes UAS, Bangalore were evaluated for seven different quantitative traits and screened for Yellow Mosaic Virus disease resistance. The data collected on seven quantitative parameters and YMV reactions were subjected for Principle Component Analysis (PCA) and eight Principal Components (PC) explained the total (100%) variation in the entire collection. Based on PCA the accessions were grouped into seven clusters. Among them, cluster II had maximum number of accessions followed by cluster V. An over view of the seven clusters indicated that genotypes coming under cluster I had better performance for days to 50% flowering, pods per plant, seeds per pod. Cultivars PHG 9, BGM 1 and DPI 2278 categorized under cluster II had better performance for plant height, branches per plant, seeds per pod, and 100 seed weight.
