Genomic Prediction of Yield Traits in Single-Cross Hybrid Rice (Oryza sativa L.).

ABSTRACT: Hybrid rice varieties can outyield the best inbred varieties by 15 - 30% with appropriate management. However, hybrid rice requires more inputs and management than inbred rice to realize a yield advantage in high-yielding environments. The development of stress-tolerant hybrid rice with lowered input requirements could increase hybrid rice yield relative to production costs. We used genomic prediction to evaluate the combining abilities of 564 stress-tolerant lines used to develop Green Super Rice with 13 male sterile lines of the International Rice Research Institute for yield-related traits. We also evaluated the performance of their F₁ hybrids. We identified male sterile lines with good combining ability as well as F₁ hybrids with potential further use in product d
