14个油用向日葵新品种（系）综合性状评价

应用灰色关联度分析方法，对14个油用向日葵新品种（系）综合性状进行评价.加权关联排序为：S27＞F53＞Y-85＞Y-86＞TO12244＞F60＞Y-103＞Y-82＞Y-78＞Y-102＞诺葵212＞Y-87＞Y-81＞Y-101. S27在所有参试品种（系）的田间产量表现较好，排在第2位，含油率排在第3位，结实率排在第2位；F53虽然产量只排在第3位，但花盘直径、结实率、百粒重均排在第2位；Y-85在所有参试品种（系）的田间产量表现最好，排在第1位；Y-87产量较低，排在所有参试品种（系）中倒数第4位，含油率是所有参试品种（系）中最低的；Y-81，产量较低，排在所有参试品种（系）中倒数第2位；Y-101在所有参试品种（系）中产量最低的.S27、F53、Y-85油用向日葵品种（系）的加权关联度较大，说明这3个品种（系）的综合性状优秀，适合生产推广；Y-87、Y-81、Y-101加权关联度排序靠后，不宜推广种植.

Evaluation of Gomprehensive Traits of 14 New Cultivars of Oilseed Sunflower

The grey correlative degree analysis was conducted to comprehensively evaluate comprehensive traits of 14 new cultivars of oilseed sunflower. The weighted grade analysis is as follows：S27〉F53〉Y-85〉Y-86〉TO12244〉F60〉Y-103〉Y-82〉Y-78〉Y-102〉Nuokui212〉Y-87〉Y-81〉Y-101.The yield of S27 is higher in all of varieties tested, ranks 2nd,the oil rate ranks 3rd, the fruiting rate ranks 2nd;the yield of F53 ranks 3rd,the diameter of flower dish, fruiting rate and hundred-grain weight rank 2nd;The yield of Y-85 is highest in all of varieties tested, ranks 1st. The yield of Y-87 is lower, ranks 4th to last and the oil rate is lowest in all of varieties tested;the yield of Y-81 ranks 2nd to last;the yield of Y-101 is lowest in all of varieties tested. The result showed that S27,F53 and Y-85 had the largest weighted correlative degree, which showed the comprehensive characters of S27,F53 and Y-85 were the best, and suitable for the production and spread, weighted correlative degree of Y-87、Y-81、Y-101 were the row behind, and unsuitable for spread.
