- 摘要:
- 为了筛选出薄皮甜瓜的优良亲本自交系，通过模糊概率法对35份自交系的生育日数、可溶性固形物含量、单株结果数、前期长势、口感、香味、裂果性、果实外观、单株产量9个指标进行综合评价，共筛选出10份性状优异的亲本自交系。排名第一的是M22-121，其单株结果数和单株产量均排名第一，分别为4.50个和1.155 kg，可溶性固形物含量为14.05%，排名第四，单瓜重为256.67 g。供试材料总体样本的数量性状中生育日数、可溶性固形物变异度较小，分别为1.75%和14.64%。变异系数较大的性状为单株结果数、单株产量、单瓜重，变异系数分别为30.28%、30.79%和35.37%，说明生产上应加强对这几个指标的选择，以获得较好的选择效果。
- Abstract:
- 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 4th， 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.
