摘要：

为了开展苦瓜强雌系育种多因素综合评估，有效选择苦瓜优异种质资源及筛选优良组合，应用灰色局势决策法，对配制的9个苦瓜强雌系杂交组合F1代的各主要性状进行综合评判。结果表明，9个组合的13个性状的权重系数大小顺序为：总产量＞单瓜重＞结果数＞横径＞单瓜长＞前期产量＞肉厚＞雌花率＞茎粗＞叶面积＞节间距＞第1朵雌花开放的天数＞主蔓第1朵雌花开放时节位。综合测度结果表明，43×K1综合效果测度值最高，为0.9343，定为优良组合重点配制。

Abstract:

In order to make the comprehensive assessment of multiple factors in gynoecious line breeding of bitter gourd, and select the excellence germplasm resources and combination, 9 bitter ground hybrids were developed by gynoecious line 43 as female line and 9 self lives as male lines. Their 13 main characteristics were made a synthetic judgment by using grey situation decision method. The results showed that the order of gray relational weight of each character was as follows: total yield＞weight per fruit＞number of fruits＞transverse diameter＞fruit length＞yield at early stage＞flesh thickness＞percentage of female flowers＞main stem diameter＞area of leaf＞node length＞abloom days of female flowers＞node of first female flower. The measure-value on comprehensive effects of 43×K1 was 0.9343. It was the most excellent combination in this test.
