灰色模糊综合评判在筛选杂交油菜信油2709的应用

运用灰色模糊综合批判对信阳市农科院自选的10个杂交新组合的品比试验结果进行分析.结果表明：新组合10个性状小区产量、株高、一次有效分枝数、主花序长度、主花序角数、主花序角长、主花序结角密度、单株总角数、每角粒数、千粒重的权系数分别为：0.140、0.106、0.085、0.097、0.102、0.091、0.101、0.092、0.092、0.095;杂交新组合的灰色模糊综合评判大小顺序为：K＞K5＞K10＞K1＞K3＞K8 ＞K2＞K6＞K7＞K9;其中K（信油2709）的综合评价值是0.6288,综合表现最大,其次是K5,综合评价值为0.6084,K9综合评价值是0.2699,综合表现最差.结果与以产量性状进行方差分析的结果来看,灰色模糊综合批判筛选的杂交新组合与实际情况基本一致.其中,信油2709在灰色模糊综合批判筛选中表现最好,.信油2709在河南省优质油菜区域试验、生产试验中表现较为突出,现已顺利通过审定,审定编号为豫审油2012001.以此筛选杂交新组合是一种较为全面的、客观的、合理的鉴定方法.

Grey Fuzzy Comprehensive Evaluation on the Application of Screening of Hybrid Rape Xinyou 2709

Grey fuzzy comprehensive critique of 10 new hybrid combinations comparison test in Xinyang academy of agricultural sciences were analyzed. The results showed that the new combination of 10 traits plot yield. plant height. branch number. length of main inflorescence. number of main inflorenscence , main inflorescence length. main inflorescence siliques density. total siliques , grains number per silique , 1000 seeds weight proportion were： 0. 140, 0. 106. 0.085. 0. 106, 0.085. 0.091. 0. 101. 0.092, 0.092, 0.095 respectively; Hybrid new combination of gray fuzzy comprehensive evaluation were： K4 〉 K5 〉 K10 〉K1〉K3〉K8〉K2〉K6〉K7〉K8; comprehensive evaluation of K4 Cxinyou 2709） value is o. 6288, it＇s the largest comprehensive performance, followed was K5, its value is o. 6084. K9 value is o. 2699. and the worst. The results to yield the results of variance analysis. the gray fuzzy comprehensive critique of screening new hybrid combination with the actual situation. Among them, the oil in the gray fuzzy comprehensive critique of the screening of Xinyou 2709 .is the third place in the analysis of variance. However. Xinyou 2709 has high quality rapeseed oil in the regional test of Henan province. production test showed more outstanding. it has been past the examination and approval, examination and approval numbers was Yushenyou2012001. It＇s a comprehensive. objective and reasonable appraisal method to screening hybrid new combination.
