多倍体育种,是主要育种途径之一。这种育种方法,可以提高产量,改进品质,增强抗性。因此,从1937年发现秋水仙素之后,许多国家相继从事这方面的试验工作,并取得了一定成绩,有不少学者曾培育出多倍体番茄,但是,其共同缺点为孕性低,在生产上难以应用。 Polyploid breeding is one of the main breeding methods. This breeding method can improve yield, improve quality and enhance resistance. Therefore, after the discovery of colchicine in 1937, many countries have successively carried out experimental work in this field and made some achievements. Many scholars have cultivated polyploid tomato. However, the common disadvantage of this method is that the pregnancy rate is low, Production is difficult to apply.
