Other claims from this paper (9)
- Observation Both rice groups had the highest GCV for grains per panicle, followed by tiller number, culm length and seedling height.
- Association Genetic advance was high for rice characters with high variability.
- Observation Both additive and non-additive gene actions contributed to characters in both rice varieties.
- Association Flowering time, tiller number and panicle length correlated positively with plant yield in Indicas.
- Association Flowering time correlated positively with plant yield in japonicas.
- Association Tiller number correlated negatively with plant yield in japonicas.
- Recommendation Panicle length was recommended as the best selection criterion for yield in both rice groups.
- Association Seedling height and culm length had considerable direct effects on yield components in both rice groups.
- Association Tiller number in indicas and flowering time in japonicas had positive direct effects on yield.
