鉴定了 1999年CIP提供的马铃薯晚疫病水平抗性群体材料 4 9个杂交组合 2 5 5 35粒实生籽及其后代无性系 ,根据晚疫病发病情况和综合性状 ,选留了早代无性系材料 12份 ,提供高代系39316 0 4和 393193 1参加了品系比较试验 ,提供 39316 0 4参加了湖北省马铃薯品种区域试验 ,均表现突出 ,较对照品种Mira增产均达显著水平 ,晚疫病抗性较对照强 ,综合性状优良。并将综合性状较优的无性系材料在杂交育种中加以间接利用 ,且筛选出一批苗头品系
The resistance to late blight of potato populations provided by the CIP in 1999 was identified as 49 resistant hybrids and 2 5 5 35 seedlings and their offspring clones. According to the incidence of late blight and the comprehensive trait, early clonal materials were selected 12 high-yielding lines 39316 0 4 and 393193 1 were included in the comparative trials of lines, providing 39316 0 4 for participating in the regional trials of potato varieties in Hubei Province, both of which performed remarkably better than those of the control variety Mira, with late blight resistance Compared with the control, the comprehensive trait is excellent. The clonal materials with better overall traits were used indirectly in hybrid breeding, and a number of inbred lines
