摘　　要：为了检测棉花芽黄基因能否作为遗传标记基因用于杂种棉制种，在１９８９～１９９７年间，鉴定了芽黄基因对其转育系经济性状的可能影响，以及芽黄转育系与陆地棉推广品种杂交的Ｆ１、Ｆ２的产量优势。初步结果表明：（１）２６个供试陆地棉芽黄突变系中，ｖ１０、ｖ１５、ｖ２０对其轮回亲本的经济性状无不良影响，证明了上述３个芽黄基因有可能作为标记基因用于杂种棉制种；（２）６个芽黄转育系与陆地栽培品种的杂种组合，其Ｆ１及Ｆ２均表现一定的产量优势。To evaluate the feasiability of virescent genes as genetic markers in producing hybrid cotton seeds, the effects of virescent genes on economic traits of their transferred lines, and the yielding heterosis of F 1 and F 2 between virescent transferred lines and upland cultivars were tested. The preliminary results were as follows: 1. Among the 26 upland virescent genes tested, v 10 , v 15 , v 20 rendered no undesirable effects on their recurrent parents. Lines containing v 10 , v 15 , v 20 had higher chlorophyll a, b contents and lower a/b ratio. In addition, their leaf color turned into green much earlier than other virescent lines, which suggested higher photosynthetic efficiency. Hence, v 10 , v 15 , v 20 may be utilized as genetic markers in producing hybrid seeds. 2. Yielding heterosis was observed in six hyhrid combinations.
