杂交水稻通过区域试验后,产量差异很明确。但各组合的主要经济性状,如有效穗、生育期、穗粒数、千粒重、结实率和抗性等这些对应性状组合间各不一样,也很不直观。针对这个问题,本文采用模糊评判法,对江西省1995年杂交晚稻区域试验的增产组合,进行综合性状的评价。产量高于CK的6个新组合,主要经济性状的综合评价都优于CK(汕优桂33)。这些组合排序分别是协优7791、协优1666、优ⅠⅤ2、新优752、优Ⅰ465、Ⅱ优46等。对照汕优桂33排第7位,综合性状最差。分析结果表明新组合产量高,且综合性状好,有其推广价值
Hybrid rice through the regional test, the yield difference is clear. However, the main economic traits of each combination, such as effective ear, growth period, grains per spike, 1000-grain weight, seed setting rate and resistance, are different from each other and are not very intuitive. In response to this problem, this paper uses the fuzzy evaluation method to evaluate the comprehensive traits in the yield-increasing combinations of the late hybrid rice regional experiment in Jiangxi Province in 1995. The six new combinations with higher yield than CK showed that the comprehensive evaluation of the main economic traits was better than that of CK (Shanyougui 33). These combinations are respectively ranked as Xieyou 7791, Xieyou 1666, Youlv2, Xinyou 752, Youliao 465, and Youyou 46. Control Shanyou Gui 33 ranked No. 7, the worst combination of traits. Analysis results show that the new combination of high yield, and good overall performance, has its promotional value
