Application of Fuzzy Probability Method in Selection of Parental Inbred Line of Oriental Melon

In order to select inbred lines, comprehensive evaluation of 9 indexes of bearing days, content of soluble solids, number of fruits per plant, early growth, taste, fragrance, fruit cracking, fruit appearance and individual plant yield of 35 inbred lines by fuzzy probability method, 10 excellent inbred lines were selected.The first was M22-121, which ranked first in the number of fruits single plant and yield of single plant, 4.50 and 1.155 kg respectively, and the soluble solid content was 14.05%ranked 4^th, and the weight of single fruit was 256.67 g. The smaller coefficient of variation of the test materials quantitative character were number of growing days, soluble solids, Its value was 1.75% and 14.64%, respectively. The traits with large coefficient of variation were the number of fruits per plant, yield per plant and single fruit weight, and the coefficient of variation was 30.28%, 30.79% and 35.37%, respectively. Strengthening the selection of these traits can obtain a good selection effect.
