从各类型稻种所配制的大量杂交中,选取了17个组合,于1982年在红光、因远两处,将亲本、杂种一代、杂种二代同时进行不同日长处理。在自然温差下研究“三性”的传递与重组。就“三性”的传递看,结果与前人大体一致,即强感光性和短的短日高温生育期为不完全显性或显性。强感温性亦有同一趋势。但随环境条件的变化,和“三性”间的互相影响,抽穗期在表现上可出现例外或甚至相反的情况。试验证明了通过“三性”的重组,选育具有广适应性光温反应型的品种是可行的,但由于“三性”是一个既有各自的独立性同时又是彼此联系相互影响的整体,又受环境的影响很大,其重组规律是错综复杂的,要作出规律性的说明,还有待进一步的研究。 Seventeen combinations were selected from a large number of hybrids of various types of rice varieties. In 1982, the parents, hybrids and hybrids were treated for different days at the same time in Hongguang and in distant places. Research on the Transmission and Reorganization of “Threeness” under Natural Temperature Difference. The transmission of the “three sexes” shows that the results are generally in line with their predecessors, that is, the strong photosensitivity and the short short-term high-temperature growth period are not completely dominant or dominant. Strong sense of warmth also have the same trend. However, with the change of environmental conditions and the interaction between the “three sexes”, there may be exceptional or even opposite situations in the performance of heading date. The experiment proves that it is feasible to breed varieties with a wide range of adaptive light and heat responses through the “three-sex” recombination. However, since the “three sexes” are a whole that has its own independence and interaction with each other , But also greatly affected by the environment, the law of its restructuring is complicated, to make a regular description, yet to be further studied.
