| Abstract: | Yunyan 77-2 and Yunyan 77-4 which were selected with sexual hybridization utilizing anticold and high-yield parent were proved that are better than GT1 on growth,yield,resistibility by primary clone trial,high clone trial and commercial planting.Yunyan 77-4 is better on cold resistance.It was recommend that Yunyan 77-2 and Yunyan 77-4 were planted on moderate on heavy cold injury stand in west rubber stand and experimental planted on moderate cold injury stand in east rubber stand of Yunnan. |
