摘要: 以番茄抗晚疫病材料CLN2037和感病材料T2-03杂交的F2分离群体的147个单株为试材, 通
过抗病性鉴定, 选择高抗单株和高感单株分别建抗、感病池。采用BSA法筛选了230条RAPD引物, 其中引物CCPB272-03 (序列为GGTCGATCTG) 在抗、感病池扩增出多态性片段CCPB272-03740 , 通过F2单株验证后证明CCPB272-03740与抗晚疫病基因Ph-3紧密连锁, 遗传距离为518 cM。

Abstract: The objective of this studywas to identify RAPD marker for resistance to late blight in tomato.BSA (Bulked SegregantAnalysis) was used to search for RAPD markers linked to late blight resistant gene Ph-3, using F2 segregating population (147 individuals) derived from a cross of CLN2037 ( resistant) and
T2-03 ( susceptible ). Two hundred and thirty decamer primers with arbitrary sequences are chosen for polymerase chain reaction amplication. One RAPD marker CCPB272-03740 ( the sequence of the primer is GGTCGATCTG) was tightly linked to the resistant gene Ph-3 and it was 518 cM from the resistant gene

Key words: tomato, late blight, RAPD marker, gene Ph-3
