我国群众性的水稻杂交育种和杂种优势利用科学实验积累了丰富的经验。为了进一步提高杂交育种的效果和更好地开展水稻杂优利用。我们于1975—1977年开展了本项试验研究。 本试验选取了矮脚南特、矮仔占、低脚乌尖等具“矮因”的水稻品种作为亲本,与其他亲本进行了多对组合杂交,并在矮脚南特×杜子籼、矮仔占×脱脱普、2150×小傢伙
The mass rice hybrid breeding and heterosis in our country have accumulated rich experience using scientific experiments. In order to further improve the effect of hybrid breeding and better utilization of rice hybrids. We conducted this pilot study in 1975-1977. In this experiment, we selected a variety of “dwarf” rice varieties such as Dwarf Nantes, Dwarf Aberdeen, and Dwarf Wudi as parents to conduct crossbreeding with other parents.
