CP24327Analysis of genetic diversity and multi-trait selection using multi-trait genotype ideotype index and genotype × yield*trait biplot in inter-subspecific cross derivatives of rice (Oryza sativa L.)

Heterosis breeding is a crucial method for breaking the yield plateau in rice (Oryza sativa L.). Inter-subspecific crosses were used in rice to diversify the parental lines to harness high heterosis. We evaluated the newly developed inter-subspecific lines for agronomic and quality traits to identify promising candidates. The inter-subspecific derivatives showed substantial genetic diversity. Selection based on multiple traits identified a few superior lines that may serve as potential restorers in hybrid development.
