14个油用向日葵新品种(系)综合性状评价

Evaluation of Gomprehensive Traits of 14 New Cultivars of Oilseed Sunflower

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.

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.
