【摘要】 按CIMMYT试验设置,对其提供的20个优质蛋白玉米(QPM)杂交种进行品比试验,从中鉴定、筛选出与当地普通玉米产量相当,抗逆性强,适应性较好的优质蛋白玉米组合。为贵州省优质蛋白玉米生产提供优质蛋白玉米杂交种。对组合的亲本充分利用,拓宽玉米育种中QPM种质资源遗传基础,加强国际合作,引进外来QPM种质,为进一步改良QPM自交系和选育新QPM自交系提供依据。更多还原

【Abstract】 According to CIMMYT experiment design, 20 QPM hybrids were compared. From those, quality protein maize combination which is equal to local ordinary maize output, strong resistance, and widely adaptive were appraised and screened. Quality protein maize hybrids were provided for the QPM production of Guizhou province. It provided basis for full use of combination parent, opening up QPM germplasm hereditary basis, strengthening the international cooperation,introducing the external QPM germplasm, improving and selecting QPM inbred lines.更多还原
