我国两系杂交稻的研究已取得重大进展,某些品种间两系杂交稻组合已在生产上试种示范,亚种间两系杂交稻也出现一些优势强大的组合。本试验选用籼籼交、籼粳交、籼广交三种类型的两系杂交稻进行比较,分析它们的生育期、株高和经济性状的优势表现,探讨其应用前景和存在问题,为选配新的两系杂交稻组合提供参考。
Significant progress has been made in the research on two-line hybrid rice in China. Some two-line hybrid rice combinations have been tested for production in some varieties, and some superior combinations have also appeared in two-line hybrid rice between subspecies. In this experiment, two types of two-line hybrid rice of indica indica, indica and japonica, indica and japonica hybrid were selected for comparison, and their advantages of growth period, plant height and economic traits were analyzed, and their application prospects and existing problems were discussed. With new two-line hybrid rice combinations provide a reference.
