Study on Heredity Laws of Keratin Membrane and Sugar Content in Semi-leafless Vegetable Pea and Their Utilization in Pea Breeding
半无叶型菜豌豆革质膜、甜度性状遗传研究及利用

It was studied for the heredity laws of keratin membrane and sugar content in semi-leafless vegetable pea. The results showed that keratin membrane character is controlled by two genes. F1 displays large keratin membranes in all fresh pods; F2 has three phenotypes, i.e. large keratin membrane, small keratin membrane and no keratin membrane with the ratio of 9:6:1. Sugar content is quantitative character fitting normal distribution. 'Xucai 1', a new semi-leafless vegetable pea variety with high yield and quality was successfully bred according to the laws. Its fresh pods taste delicious. Its extremely developed tendrils can be sold as top grade Longxu vegetable. The tender stems and leaves are also high quality vegetable.
