摘要:
植物细胞核雄性不育系具有易于恢复但保持困难的特点。根据广西南部冬季无霜冻的气候特点,在广西南宁进行了一年生陆地棉细胞核雄性不育系洞A的三年露地栽培。结果表明:二、三年生洞A在5月上旬开花、6月下旬吐絮,这是一年生洞A在相同环境条件下难以达到的;与一年生洞A相比,二、三年生洞A的子指、单株铃数、产量显著增加,但单铃重、衣分显著下降,僵瓣率显著增加;纤维品质基本没有显著变化。说明利用陆地棉细胞核雄性不育系在南亚热带的宿生栽培进行良种繁育具有较好的前景。
Abstract:
Genic male sterile (GMS) lines of plant has the characteristic which is easy to restore but hard to maintain. On the basis of frostless climate characteristics in winter of Nanning,Guangxi,“Dong A” GMS lines in annual upland cotton was field cultured for three years. The results showed that,biennial and triennial “Dong A” cotton could flower in early May and open bolls in late June,which were hard for annual “Dong A” in the same environment;comparing to annual “Dong A” cotton,the 100seed weight index,bolls per plant,and yield of biennial and triennial “Dong A” cotton were significantly increased,but the boll weight and the lint rate of them were significantly decreased,and the dead locule rate of them was significantly increased; the fiber quality of biennial and triennial “Dong A” cotton was basically not changed significantly. It was concluded that,the utilization of perennial cultivation on GMS lines for stock breeding had a good prospect in the south subtropical zone.
