巴西橡胶新种质鉴定及利用研究初报

Primary Study on Identifying and Utilizing New Germplasm of Hevea brasiliensis

对从科特迪瓦和CIRAD -CP引进的 198个巴西橡胶新种质和 10个IRCA橡胶树新品种在云南植胶区的农业气象条件下进行适应性鉴定。这些新种质和新品种生长表现良好。经试割 ,新种质几乎无胶可收 ,新品种试割6个 ,有 4个产量超过RRIM60 0 ,抗寒能力普遍差。

It were studied that 198 kinds of germplasm from Cote d“ Ivoire and CIRA—CP and 10 varieties of IRCA under condition of planting rubber The growth of the germplasm and varieties represents all right The result of trying tapping shows that the germplasm has nearly no latex ,the yield of 4 new varieties exceeds the yield of RRIM 600 among 6 tapped varietie, the resistance to cold is low at large
