In this study, we tried to breed alloplasmic and autoplasmic Brassica napus-Raphanus sativus monosomic addition lines (MALs) mediated by the synthetic amphidiploid Raphanobrassica (RA89 and Rb63 lines), and also to survey favorable characteristics for B.napus breeding using them.In 2007, alloplasmic MAL with 8 types (a～i) except for the h-type and autoplasmic MAL with complete 9 types were produced using 175 RAPD markers specific to R-genome. In characteristics of the MALs, most of alloplasmic MAL having the radish cytoplasm showed male sterility and only the a-type produced normal flower and had a high pollen fertility (88%), suggesting to have fertility restoring gene(s) for male sterility in alloplasmic line.In 2008, we studied (1) identification and evaluation of clubroot resistance (CR) of radish chromosome, and (2) embryogenesis of MAL with d-chromosome of radish inducing low seed fertility. (1) Among the 9 types of MALs, only the c-type showed strong resistance (IC=73%, ID=0.7), … More on the other hand, other types showed complete susceptibility (IC=100%, ID=3.0). The result suggested that the major CR gene(s) may be located on the c-chromosome of the radish genome. (2) In 3 weeks after backcrossing of MALs × B.napus, embryos in all types except for the d-type were grown from torpedo (T) to mature (M) stage, on the other hand, one in d-type were globular (G) to heart (H) stage following to chlorosis. It was assumed that the low seed fertility in the d-type was induced by embryo underdevelopment.In 2009, for development of disomic addition lines (DALs), we studied ; (1) improvement of male transmission rate of radish chromosome in MALs by limited pollination, and (2) crossing with the same addition lines by both normal and limited pollination methods. (1) the 7 types except for the b- and c-types were advanced male transmission rate of alien chromosome by limited pollination (7.0～70.3%) in comparison with normal one (2.9～54.3%). (2) a large number of seed were successfully obtained with a range of 13.2 seeds per pod for the i-type (totally 787 seeds) to 1.7 for the g-type (132 seeds). From results of (1) and (2), it may be developed DALs in the near future. Less

本研究以人工合成的双二倍体萝卜为材料，通过诱导异源和同源细胞质的甘蓝型油菜-萝卜单体异附加系，（RA 89和Rb 63系），并调查利用它们进行B.napus育种的有利特性。利用175个R基因组特异性RAPD标记，获得了除h型外的8种（a~i）异质MAL和9种完整的同源MAL。2008年，我们开展了以下研究：（1）萝卜染色体抗根肿病鉴定与评价，（2）萝卜染色体抗根肿病鉴定与评价，（3）萝卜染色体抗根肿病鉴定与评价，（4）萝卜染色体抗根肿病鉴定与评价，（5）萝卜染色体抗根肿病鉴定与评价，（6）萝卜染色体抗根肿病鉴定与评价，（7）萝卜染色体抗根肿病鉴定与评价，（8）萝卜染色体抗根肿病鉴定与评价，（9）萝卜染色体抗根肿病鉴定与评价，（10）萝卜染色体抗根肿（2）萝卜d染色体的MAL胚胎发生诱导低育性种子。(1)在9种MALs中，只有C型表现出较强的抗性（IC= 73%，ID=0.7）， ...更多信息 而其他类型则完全敏感（IC= 100%，ID=3.0）。结果表明，萝卜的主效CR基因可能位于萝卜基因组的C染色体上。(2)回交3周后，除d型胚外，其余类型胚均从鱼雷期（T）发育到成熟期（M），d型胚中有1个胚从球形期（G）发育到心形期（H），并随失绿而退化。2009年，为了培育二体附加系（DALs），我们研究了：（1）通过有限授粉提高萝卜MAL染色体雄性传递率;（2）通过正常授粉和有限授粉方法与相同附加系杂交。(1)除B-和C-型外，其余7种类型的有限授粉雄传率（7.0~70.3%）均高于正常授粉雄传率（2.9~54.3%）。(2)成功地获得了大量的种子，I型的每荚13.2粒种子（总共787粒种子）到G型的每荚1.7粒种子（132粒种子）。根据（1）和（2）的结果，在不久的将来可能会开发DAL。少
