Breeding of New Variety of Oil Flax Baya 13

Baya 13 was a new oil flax cultivar selected from fine indviduals bred through the hybrid offsprings of female Jinya 7 ~ male 89 -46 -884 -901. This new cuhivar was experimented in the re- gional trial in Zhangjiakou from 2007 to 2009. The results showed that the average yield of six experimen- tal points in three years was 1659 kg/hm2, increased 8.32% compared with CK （ Longya 8, of which the yield was 1531.5 kg/hm2） , and significantly increased 10. 27% compared with Baya 7 （of which the yield was 1320 kg/hm2） . The seedlings of Baya 13 grew well and tidily, with plentiful branches and fruits, and high resistance to lodging, drought and flax wilt. Baya 13 was proved to be suitably planted in cold, semi- arid regions in Hebei, Shangxi, Inner Mongolia, Ningxia and Gansu.
