Abstract: Semi-leafless pea is the mutant of common pea. Cross experiments between semi-leafless pea and common pea were carried out to find out heredity of semi-leafless gene. The results showed that semi-leafless is governed by a recessive gene af . It is linked with i (green cotyledon) and lf (low initial flowering node) on the first chromosome in pea , and the order of them is lf , af and i , i . e. af is between lf and i . Cross-over value between af and i is 6.80 % , and 36.74 % between af and lf . A new semi-leafless vegetable pea cultivar with super-high yield and high nutritional quality. ‘Xucai 1’was bred and selected. 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. Significant value of af in pea breeding was conclusive.
