First, the source: the original code 72C Department 36-3. For the Qinghai Academy of Agriculture and Forestry Haibei point in 1969 from “the oil” in the separation of precocious pomes, after years of system selection. Second, the characteristics and characteristics: a small cabbage-type rapeseed early special strains. Strong spring, pale green leaves, seedlings erect, seedling short, three true leaves that began to budding moss. Selfing can not be normal and strong. Spring planting in Xining, bud thistle emergence 20-25 days, flowering 24-29 days, the growth period of 85 days. Plant height of 100-110 cm, the starting point of branches 20-25 cm, stem hard, good erection, suitable for mechanical harvesting. In the case of close planting, a branch of 2.9, a second branch. The results of a single plant 82.1, the main sequence length of 61 cm, the main order of the fruit 40, the main sequence length and the main sequence of the number of fruit and plant each accounted for about half of the total number of fruit. In the middle of the main sequence, there are 17.2 fruit within 20 cm, fruit length 6 cm, 21 fruits per fruit, yield 2.2-6.6 g per plant. Larger seeds, seed coat
