我们玉米育种工作已经和平谷县农科所合作多年,目标是培育出高产、稳产的三交种及其中间产品——单交种,以便降低种子价格,延续种子使用年限,方便群众。几年来,我们征集了相当数量的地方品种作为选育一环系的材料,也引进了一定数量的国内外优良自交系、杂交种作为选育二环系的材料。目前已选育了相当数量的行系,大部分趋于稳定,每年可测交、组配500-1000个组合进行鉴定,已评选出10多个组合正在进行品
Our corn breeding work has been cooperating with Pinggu County Agricultural Science Institute for many years. The goal is to breed three cross-breeding varieties and their intermediate products - single cross breed with high yield and stable yield, in order to reduce the price of seeds, extend the useful life of the seeds and facilitate the masses. In recent years, we collected a considerable number of local varieties as a material for breeding a ring system, but also introduced a number of good inbred lines at home and abroad, and hybrids were used as materials for the breeding of the second ring system. At present, a considerable number of lineages have been bred and most of them have been stabilized. They can be tested annually with groups of 500-1000 and identified. More than 10 combinations have been selected
