New Hybrid Rice Varieties Boost Winter Waterlogged Field Yields Dramatically!
The researchers studied how different types of paddy fields affect the yield of mid-season hybrid rice. They found that certain hybrid rice combinations can produce high yields in winter waterlogged fields by increasing seed setting percentage and grain weight. The key characteristics of high-yield rice in these fields include a specific number of spikelets per panicle, tillers per hectare, productive panicles, seed setting percentage, grain weight, spikelet number, leaf area index, and single ear weight. These findings help rice breeders identify high-yield combinations and production areas select suitable rice varieties for different types of paddy fields in winter waterlogged areas.
