按农作物最佳遗传优势部位搞定位选种,是选种科学的一项新技术。所选出的种子能把一个品种所有优良性遗传给下一代,即可经济有效增产丰收。试验证明:水稻穗子最优遗传部位种子的发芽率为100％,插秧及秧苗生长整齐健壮,抗逆性强,分孳快,可增产10％以上;小麦最佳遗传部位留种,成熟齐,增产8—11％;玉米最佳遗传部位留种可增产6.2—8.7％,成熟
According to the location of the best genetic predisposition for crop selection, selection of science is a new technology. The selected seed can give all the goodness of a variety to the next generation, yielding economic and efficient yield. The results showed that the germination percentage of the optimal genetic parts of rice ears was 100%, the transplanting seedlings grew neatly and stably, the resistance was strong, Yield 8-11%; the best genetic parts of corn to stay seed yield 6.2-8.7%, mature
