超级杂交早稻陆两优996亲本感温特性研究
Study on the Characteristics of Sensitive to Temperature of Super Hybrid Rice(Oryza sativa L.) Luliangyou 996's Parent
摘要
Abstract
[Objective] The characteristics of sensitive to temperature of super hybrid rice Luliangyou 996' s parent, Lul8S and R996, were studied and discussed, especially studied the relationship between the days from sowing to heading and accumulative temperature, making for suitably arranging the sowing date of its parent and predicting and controlling its early flowering date. [ Method] Lul8S was sowed at March 26, April 14, May 21, June 7 , June 21 resp. And R996 was sowed at March 26, April 20, May 27, June 12, June 29 resp.. The days from sowing to heading of Luliangyou 996' s parent sowing at early season and low temperature condition and late season and high temperature condition were recorded resp. , and observed their development dynamic state, moreover, the correlation and regression analysis were carried out between accumulative temperature and its stability of Luliangyou 996' s parent at each stage of whole growth period and the days from sowing to heading. [ Result] The temperature sensitive level of R996 was six, which was classified as medium temperature sensitive variety. The temperature sensitive level of Lul8S was seven, which was classified as strong temperature sensitive variety. The characteristics of sensitive to temperature had some difference between R996 and Lul8S . [Conclusion] The study provides a guidance for solving blooming of flowering at different times of parent when using Lul8s and R996 to produce seeds.关键词
