 ABSTRACT

In the present investigation 18 Spanish bunch groundnut genotypes were used for variability, character association and path analysis studies in 19 plant characters. In general  higher GCV  and  heritability estimates coupled with high genetic advance as per cent of mean recorded for LLS severity, reducing sugar and non-reducing sugar indicated lesser influence of environment in expression of these characters and these characters are controlled by additive gene effect, hence, amenable for simple selection. Pod yield per plant exhibited positive significant association with number of pods per plant, total sugar, kernel yield, non reducing sugar, test weight, SCMR, harvest index, oil content and shelling per cent, whereas, LLS severity, reducing sugar, stomata frequency and size showed negative  significant association. Total sugar, kernel yield, stomata length, LLS severity, test weight, SCMR, days to maturity and oil content exerted the positive direct effect on pod yield, whereas, non-reducing sugar, stomata frequency, shelling per cent and harvest index had maximum indirect direct effects on pod yield per plant. Thus, due emphasis should be placed on these characters while selecting genotypes for high yield with LLS tolerance in groundnut

Key words: Genetic variability, Heritability, Character association and Path analysis
