Description The genetic divergence study in 46 maize inbred lines was conducted based on Mahalanobis D2 statistics by using Tocher’s canonical (vector) and Euclidean methods at Maize (Zea mays L.) Breeding Research Sub-Station, Poonch during 2009-2011. The genotypes were grouped into seven clusters by both the methods of divergence study. The grouping of genotypes in different clusters was beyond their geographic origins. This indicated appreciable amount of diversity present in the inbred lines under study. Canonical (vector) analysis suggested that plant height, stem girth and number of leaves per plant had contributed maximum towards total variability in the lines. 3D plotting of individual genotypes, based on principal component analysis scores and Euclidean distance matrix, showed that the PMS134 was the most diverse inbred with CML324 followed by M8-3, CML158, 6152 and CML399. These diversely related inbred lines can be utilized as parents in maize breeding programme to isolate desire hybrids for yield and component characters.
