Abstract:
Study on genetic parameters, character associations and path coefficients of 107 rice genotypes for anaerobic germination traits revealed high variability, heritability and genetic advance as per cent of mean for seedling vigour index. High heritability and genetic advance as per cent of mean was also recorded for shoot length, root length, seedling dry weight and anaerobic response index. Further, all anaerobic germination traits studied had recorded high positive association with anaerobic response index. Among these, shoot length had recorded high positive direct and indirect effects and is identified as effective selection criterion for improvement of anaerobic response index towards tolerance to anaerobic conditions during germination for use under direct seeding.
