| dc.description.abstract | Genetic behavior and the relationships of quantitative and qualitative characters were studied using five United States rice varieties and the F2 and F3 generations of six of their crosses. Biometrical data indicated that genetic variations for plant types, yield components and grain yield were evident. Partial dominance was indicated for both shorter flag leaf and shorter second leaf. Flag and second leaf width indicated partial dominance for broader leaves. Flag leaf angle indicated partial dominance for open angle whereas second leaf angle also showed partial dominance for broader angle. Flag and second leaf length showed positive correlations with yield and some components of yield suggesting that they may have an influence on yield. Flag leaf width had a positive relationship with second leaf width. Although flag and second leaf width showed positive correlations with some of the yield components, they did not show significant relationships with yield. This may have been due to negative correlation with culm numbers. Both flag and second leaf angle showed negative correlations with grain yield indicating that narrow leaf angle influence grain yield. ... | en |
