High-yield cultivation of two-line rice
Two-line rice has the characteristics of early growth and rapid development, smooth color conversion in the middle stage, long post-ripening period, fertilizer resistance, large panicle and many grains, better rice quality, stable and high yield and obvious advantage in yield increase compared with three-line rice. it has been popularized and applied in various areas in recent years. In practice, we have conscientiously grasped the "six changes" measures for high-yield cultivation, gave full play to the high-yield advantages of two-line rice, and achieved gratifying results. 1. Improve the technique of raising seedlings and cultivate strong seedlings according to the characteristics of small elasticity of seedling age of two-line rice. Row

How to carry out Rice breeding
In the process of hybrid rice breeding, the sterility of rice male sterile lines is affected by photosensitive factors. Male sterile lines are generally sterile under long sunshine from April to September and fertile under short sunshine from September to April next year. Therefore, the yield of "two-line hybrid rice breeding" is more than 20% higher than that of "three-line hybrid rice breeding", and it overcomes the problems of singleness of sterile cytoplasmic source and great limitation of heterosis utilization. The genetic affinity between indica and japonica subspecies is affected by its affinity substance.

Peiza 67 (Rice)
In the basic situation, we used the low temperature sensitive genic male sterile line Peiai 64s and the self-selected high quality indica-japonica progeny line G67 (Copslo17/ milligram old / / Xinxiu 299) to select a new two-line hybrid rice combination Peiza 67 with high quality, high yield and high resistance. The characteristic Peiza 67 participated in the joint evaluation of two-line hybrid rice in Guangdong Province, and its yield was 6.84t/hm2, which was the same as that of Shanyou 63, and in 1996 and 1997, it participated in the joint regional test of hybrid rice, and the yield was 6.29 and 6 respectively.
