Abstract

Genetic variability, heritability and genetic advance were investigated in 96 melon (Cucumis melo L.) genotypes from 4 horticultural or 6 varietal groups using 10 quantitative traits. The results of the analysis of variance showed that there was enough variation among the genotypes for all the attributes. The highest phenotypic and genotypic coefficients of variations (PCV and GCV) were observed for node to first male flower (40.98 and 31.3%), average fruit weight (36.23 and 30.8%) and total soluble solids (28.01 and 26.67%), while days to first male flower anthesis (10.49 and 8.85%) and days to first female flower anthesis (8.86 and 7.4%) had the least coefficients of variations. The high difference between PCV and GCV estimates exhibited that environmental factors had more influence on trait expression. High heritability coupled with high-moderate GAM was observed for TSS and flesh thickness, indicating that additive genes govern these traits and that these traits could be effectively breed through selective improvement. Nine promising genotypes were identified for further breeding for earliness and lateness in order to extend melon supply in the market.

利用形态特征解读甜瓜的遗传变异

利用10个数量性状对4个园艺类群或6个品种类群的96个甜瓜(Cucumis melo L.)基因型的遗传变异、遗传力和遗传进展进行了研究。方差分析结果表明，各性状基因型间存在足够的变异。表型变异系数(PCV)和基因型变异系数(GCV)以节位至首雄花的变异系数(40.98和31.3%)、平均果重的变异系数(36.23和30.8%)和总可溶性固形物的变异系数(28.01和26.67%)最高，而至首雄花开花的变异系数(10.49和8.85%)和至首雌花开花的变异系数(8.86和7.4%)最小。PCV和GCV之间的差异表明环境因素对性状表达的影响更大。TSS和肉厚的遗传力高，GAM偏高，说明加性基因控制着这两个性状，可以通过选择性改良进行有效育种。为扩大甜瓜市场供应，确定了9个有潜力的早熟和晚熟基因型。
