摘要
通过 3 0a来杂优群体构建、改良和完善以及杂交种选育的经验和成果对群体育种的理论进行了深入研究和探讨。在 4个综合种选系集团的基础上通过不断的优良种质引进和创新 ,构建了Reid、Lancaster、Dom、唐山C团和唐山D团 5个杂种优势群体和Reid×Dom、Lancaster×Dom、C×D等杂种优势模式 ,并育成了以唐单 4号、唐单 6号、唐单 9号、唐玉 1号、唐玉 2号、唐玉 10号、津唐 1-4号等为代表的一批生产主栽品种 。
Based on the results of thirty years heterosis populations construction and elite hybrid breeding of maize, the empiristic and theoretic population breeding of maize was discussed. Through continuous introduction of elite maize germplasms into the four basic integrate lines, five heterosis populations, Reid, Lancaster, Dom, Tang C, and Tang D, and three heterosis models, Reid X Dom, Lancaster X Dom, and Tang C X Tang D, were constructed. As a consequent, at least seven wide planted hybrids were selected from these populations.
