Abstract

The experiment was conducted to determine the varietal difference and relationships among seed quality characters in ten West African rice seeds. Eight seed quality traits (seed germination, seedling vigour index, speed of germination index, seedling emergence, seedling length, seedling dry weight and energy of germination) were subjected to analysis of variance, correlation and stepwise multiple regression. Results showed that varietal effects were highly significant in all the seed quality traits. ITA 230 (FAROSO) had the best seed germination, seedling emergence, seedling vigour index, speed of germination and energy of germination. This was followed by TOX 4004-43-12-1 with relatively high seed germination, speed of germination and energy of germination. Seedling length, seedling vigour index, speed of germination and energy of germination showed positive and significant correlations with seed germination and seedling emergence. Seedling emergence also correlated significantly with seed germination; while seedling vigour index, speed of germination and energy of germination had high positive correlations with one another. Stepwise regression showed that seed germination was a good predictor of seedling emergence, while speed of germination was the best predictor of seed germination. However, research on the appropriate methods of breaking seed dormancy in CISADANE (FARO 51), WAB189B-B-B-HB, WITA1 and WITA12 should be intensified.
