通过３０ｋｅＶ不同剂量的Ａｒ＋注入和ＤＮＡ溶液浸滴法将比克氏棉和红麻ＤＮＡ导入泗棉２号。结果表明：离子注入可显著地促进外源ＤＮＡ导入受体，增加受体后代性状的变异频率和变异类型，而且多数变异可迅速趋于稳定。在供试剂量中，以２×１０１５Ａｒ＋／ｃｍ２介导外源ＤＮＡ引起受体性状变异的频率最高，达１６．２％。经选育已获得了一批抗枯萎病、早熟、种子少腺体和优质等各具特色的陆地棉新种质系。 The Beak cotton and kenaf DNA were introduced into Simian No.2 by Ar + injection of 30 keV and DNA dipping method. The results showed that ion implantation significantly promoted the introduction of exogenous DNA into the receptor and increased the variation frequency and variation type of the trait of the progeny of the recipient, and most of the variation could quickly stabilize. In the test dose, the frequency of 2 × 10 15 Ar + / cm 2 mediated foreign gene mutation caused the highest frequency, up to 16.2%. After selection, we obtained a series of new germplasm resources of G. hirsutum, which are resistant to Fusarium wilt, precocious, less gland and high quality.
