对13个甜瓜种质材料的主要生物学特性、品质、产量和抗病性等进行了研究和鉴定。结果表明,东方型薄皮甜瓜232#、961#和962#均属于早熟品种,具有较强的生长势和较高的单株结果率,其中品系962#获得最高的产量(176kg/667m2)和最高的单株结果数(5.6个/株),品系961#具有最高的果肉含糖量(最高达14.5%)和最佳的果实风味(五级)。厚皮甜瓜品系中的光皮类型比网纹类型相对具有较强的生长势和较高的结果率,同时果实风味和产量也普遍优于网纹类型,其中223#、1054#、963#和Ten-Me具有丰产的优势(超过1200kg/667m2),并属于优质甜瓜品系(果肉风味四级以上)。网纹品系卫1225#获得最低的产量和最少的单株结果数(1.1个/株),但具有最大的单果重(平均1.03kg)。对抗病性的测定结果表明,网纹类型普遍抗病性较差,光皮类型中部分品种则具有较强的抗病性,东方型甜瓜抗病性最强,是极好的抗病育种材料,同时也是丰产、早熟性育种的首选亲本材料。此研究结果为下一步的育种工作提供了良好的物质基础。
The main biological characteristics, quality, yield and disease resistance of 13 muskmelon germplasms were studied and identified. The results showed that oriental thin melon 232 #, 961 # and 962 # belong to precocious varieties with strong growth potential and high single fruit yield, in which the highest yield (176kg / 667m2) and highest (5.6 plants per plant). Line 961 # had the highest sucrose content (up to 14.5%) and the best fruit flavor (grade 5). The light skin types in muskmelon lines had stronger growth potential and higher fruiting rate than the textured lines, and the fruit flavor and yield were also generally better than the textured ones. Among them, 223 #, 1054 #, 963 # and Ten-Me has the advantages of high yield (more than 1200kg / 667m2), and belongs to the quality of melon strains (fruit flavor more than four). Textured line Wei 1225 # obtained the lowest yields and the lowest number of single plants per plant (1.1 plants per plant), but with the largest single fruit weight (1.03 kg average). The results of the disease resistance test showed that the general resistance of the reticulate type was poor and that of some species of the light-skin type was strong resistance, while the oriental melon had the strongest resistance and was an excellent disease-resistant breeding Materials, but also the first choice for high-yielding and precocious breeding. The results of this study provide a good material basis for the next breeding work.
