Intra-varietal variability in Komadan seedlings

Abstract

A study on the association of various quantitative characters and the pattern of variability in Komadan seedlings showed that considerable amount of variation in eight morphological characters. The seedling S71 showed the maximum values for collar girth at nine months age, number of leaves at nine and twelve months age. The seedling S68 had maximum height and collar girth at nine months age and number of leaves at nine and twelve months age. The seedling S100 was found to have the highest collar girth at twelve months age, number of leaves at nine months and twelve months age. The maximum coefficient of variation was recorded for number of leaves at twelve months age. High significant correlation was noted among eight morphological characters. Number of days for germination was positively correlated with number of days for splitting of leaflets and height of seedlings was positively correlated with collar girth. Number of days for splitting was negatively correlated with collar girth and height of seedlings. Selection based on the above characters will be useful in crop improvement programmes using Komadan as the information recorded on this ecotype were scanty.
