利用高稳系数法分析杂交水稻品种高产稳产性

目的]为HSCi法在杂交水稻高产稳产性分析中应用的可行性提供科学依据.方法]采用高稳系数法,对2013年度长江上游中籼迟熟组A组国家水稻品种区域试验汇总报告进行综合分析和评价.参试11个水稻品种分别为竹优1013、鹏两优187、泸优257、内香5A/川恢907、T优1655、瑞华218、德香047A/R4923、Ⅱ优838、天龙优1375、绿优4923、德润1A/金恢8023.试验点分布在16个地区,分别为黔东南、黔西南、贵州贵阳、贵州遵义、陕西汉中、四川巴中、四川广元、四川绵阳、四川内江、四川泸县、四川双流、云南红河、云南文山、重庆涪陵、重庆巴南、重庆万州.结果] HSCi分析结果表明,具有高产、稳产性的品种有德香047A/R4923、绿优4923、德润1A/金恢8023、泸优257及内香5A/川恢90.HSCi综合体现了参试品种高产与稳产性,完全可表达出Si、CV的测度,在水稻区域试验中对其高产稳产性的评估具有极高的可靠性与实用性.结论]德香047A/R4923、绿优4923、德润1A/金恢8023、泸优257及内香5A/川恢90属高产、稳产品种.同时也证实HSCi法比方差分析更能客观反映水稻品种高产稳产性,计算更为简单.

Analysis of High Yield and Yield Stability of Hybrid Rice Cultivars by Using High Stability Coefficient Method

Objective] The aim was to provide a scientific basis for the feasibility of application of High Stability Coefficient Method（HSCi method） in high yield and yield stability analysis of rice.Method] The summary report of national rice cultivars regional test of A group of the indica and late mature group in the upper Yangtze river in 2013 were analyzed and evaluated comprehensively by HSCi method.The 11 tested rice cultivars were Zhuyou 1013,Penglaingyou 187,Luyou 257,Neixiang 5A/Chuanghui 907,Tyou 1655,Ruihua 218,Dexiang 047A/R4923,Ⅱ you 838,Tianlongyou 1375,Lvyou 4923,Derun1A/Jinhui 8023,resp..The 16 tested points were the southeast of Guizhou,the southwest of Guizhou,Guiyang of Guizhou,Zunyi of Guizhou,Hanzhong of Shaanxi,Bazhong of Sichuan,Guangyuan of Sichaun,Mianyang of Sichuan,Neijiang of Sichuan,Lu county of Sichuan,Shuangliu of Sichuan,red river of Yunnan,Wenshan of Yunnan,Fuling of Chongqing,Banan of Chongqing,Wanzhou of Chongqing.Result] The analysis results by HSCi method showed that the hybrid rice cultivars with high yield and good quality were Dexiang 047A/R4923,Lvyou 4923,Derun1A/Jinhui 8023,Luyou 257 and Neixiang 5A/Chuanghui 907,resp..HSCi method embodied the high yield and yield stability of tested cultivars synthetically,gave fully expression to the measure of Si and CV,had extremely high reliability and practicability to evaluate rice high yield and yield stability in rice regional test.Conclusion] Dexiang 047A/R4923,Lvyou 4923,Derun1A/Jinhui 8023,Luyou 257 and Neixiang 5A/Chuanghui 907 belong to high yield and good quality cultivars.At the same time,the study also proves that HSCi method better objectively reflects the high yield and good quality rice cultivars than variance analysis,and its calculation is more simple.
