为了提高小麦杂交结实率,促进育种工作的进行,我们用普通小麦对五种小麦杂交方法进行了比较研究,同时进行了少量小黑麦、大麦、莜麦、碱草等远缘杂交,试验结果证明:装袋自由授粉,方法简便、速度快、结实率高、质量好,是多快好省地开展小麦有性杂交工作的好方法。一,五种杂交方法介绍1、装袋自由授粉法具体做法是父母本隔行相 In order to improve the seed setting rate of wheat and promote the breeding work, we compared the crossbreeding methods of five wheat varieties with common wheat and carried out distant hybridization with a small amount of triticale, barley, barley, It is proved that bagging is free and pollination. The method is simple, fast, high in seed setting rate and good in quality, and is a good method to carry out sexual hybridization in wheat more quickly and economically. First, the introduction of five kinds of hybrid methods 1, bagging free pollination method is the specific practice of parents, interlacing
