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.
