小麦剪颖杂交方法,手续简便,省工省时,花粉新鲜,结实率高。据51个组合统计,去雄2,953朵花,授粉结实2,475粒,结实率为83.8%。过去采取不剪颖杂交方法,从整穗、去雄、采粉、授粉,费工费时,结实率还低。杂交一个穗子,多的结实5—8粒,少的结实1—2粒或不结实。现在采用剪颖杂交方法,半天去雄30多穗,600余朵花,由于结实率高,每个组合杂交的穗数,由原来的4穗减少为2穗,从而缩短了时间,提高了工效。这个方法简便,容易为广大农村干部、知识青年、贫下中农掌握,有利于开展群众性育种活动。这种方法的程序是:
Wheat shear-method hybridization, simple procedures, labor-saving time, pollen fresh, high seed setting rate. According to the statistics of 51 combinations, 2,953 flowers were excised, 2,475 were pollinated and strong, and the seed setting rate was 83.8%. In the past to take non-shear Ying hybrid method, from the whole spike, to male, picking, pollination, labor costs, seed setting rate is low. One ear of hybrids, 5-6 grains more robust, less robust 1-2 grains or not strong. Now using the method of shear-resistant crosses, half a day to over 30 spikes, more than 600 flowers, due to high seed setting, the number of each combination of hybrid spikes, reduced from the original 4 spikes to 2 spikes, thereby shortening the time and improve the work efficiency . This method is simple and easy to grasp for the broad masses of rural cadres, young intellectuals and poor middle peasants, and is conducive to carrying out mass breeding activities. The procedure for this method is:
