摘　　要：以从美国威斯康星大学引进的叶用芥菜胞质雄性不育系叶用4-4为母本,以泰国清迈大学选育出的8个优良叶用芥菜品种为转育父本,杂交后连续回交4代(BC4),再将BC4与优良叶用芥菜品种40R2-3-4配制8个杂交组合,其中2个组合(4-4 × 19-H-12)×40R2-3-4和(4-4 × 2R2)×40R2-3-4结球率为100％,产量比商用品种分别高34％和13％,比其亲本分别高25％和5％。Cytoplasmic male sterility line of leaf mustard ( Brassica juncea L. ) , which received from Wisconsin University, U. S. A. , was crossed with eight good varieties of leaf mustard which were selected by Chiang Mai University. Then F1 crosses were backcrossed with the male parents for four generations ( BC4 ). These BC4 lines were crossed with good variety of leaf mustard 40R2-3-4. The eight F1 were tested in comparison with commercial varieties in winter 1998. Most F| hybridized combinations did not form head, and bolted early. However, two F1 hybridized combinations, (4-4 × 19-H-12) ×40R2-3-4 and (4-4 ×2R2) ×40R2-3-4 formed 100 % head and yielded 34 % and 13 % higher than average yield of commercial varieties respectively, and 25 % and 5 % higher than their parent 40R2-3-4, respectively.
