58份南瓜杂交组合果实性状调查与分析

Investigation and Analyses of Fruit Characters of 58 Pumpkin Hybrids

对58份南瓜（Cucurbita moschata Duch.）杂交组合（F1）的主要果实性状进行了测定与分析。结果表明,不同杂交组合的性状差异较大,其中果肉厚度为1.4-5.4 cm、果形指数为0.7-4.0、可溶性固形物含量为8.9%-16.9%;果皮主色大部分为土黄色,果肉颜色多为深黄和浅黄色,果肉肉质以中等致密和疏松为主、综合品质属中等。58份组合的果实产量最高的是009-1×浙江七叶组合（2 756.9 kg/667 m^2）,产量最低的是450×十姐妹组合（182.8 kg/667m^2）,平均产量为828.4 kg/667m^2。该结果为南瓜新品种选育提供了依据,并在理论与实践上对今后的南瓜育种工作提供了一定的指导借鉴。

The fruit characters of 58 pumpkin （Cucurbita moschata Duch.） hybrids （F0 were measured and analyzed. The results showed that there were great differences among them. The thickness of flesh was varied from 1.4 to 5.4 cm. The fruit shape index was 0.7-4.0. Solids content was varied from 8.9% to 16.9%. The main color of fruit peel was generally earth yellow. Pulp color was deep yellow and light yellow. The pulp texture was mainly medium density and osteoporosis, with medium comprehensive texture. The 009-1×Zhejiangqiye hybrid had the highest yield（2 756.9 kg/667 m^2）, while 450×Shijiemei had the lowest yield （182.8 kg/667 m^2）. The average area yield of all hybrids was 828.4 kg/667 m^2. It will provide basis for breeding new pumpkin varieties in theory and practice.
