丝瓜果肉耐褐变种质资源的筛选及初步应用

摘要

We analyzed flesh browning characteristics of 117 luffa (Luffa cylindrica L.) germplasm resources. The results showed that, the variation coefficient of all the 117 luffa germplasm resources was 82.32%, and ten of them were highly resistant to browning, while 73.50% of them were easy to browning. And the germplasm resources, which were highly resistant to flesh browning, were in cylinder shape. Flesh anti-browning trait of F1 hybrids was obviously improved by taking the materials highly resistant to browning as female parent.%对117份丝瓜种质资源的果肉褐变特征进行考察，结果表明，丝瓜果肉褐变性状变异系数高达82.32%；筛选出极耐褐变材料10份，占8.55%，易褐变资源占总资源的73.50%；极耐褐变资源瓜形多为圆筒形；耐褐变材料作为亲本之一所配制组合的褐变指数均较低，尤其是以极耐褐变材料作为母本时效果更为明显。
