Discussion

Observational analysis reveals positive associations of drought tolerance traits with yield in rice, highlighting key genetic factors.

Path analysis showed that root thickness and root length positively impacted grain yield under drought stress conditions.
Correlation analysis indicated significant associations between grain yield and drought tolerance traits like filled grains and productive tillers.
This study utilized generation mean analysis across six generations to examine the genetic basis for yield traits in rice.
Findings suggest the importance of specific traits in enhancing yield in drought conditions, with gene interactions noted.

Ambikabathy et al. (2025) studied this question.
