| 摘 要： | 结合四川地区生态环境,将高产、优质、多抗、广适作为育种目标选育玉米新品种。根据基因重组的原理,把含有热带种质的优良地方种与富含抗病、抗倒及耐旱等优良基因的PB类种质融合在一起,以此作为育种创新策略。成功选育出配合力高,抗病、抗逆性强、适应性广的优良自交系‘LSC107’,与自育系‘宜99-19’杂交育成玉米新品种‘万德1号’。试验结果表明:该品种产量高且稳产性好,品质优,抗病、抗倒伏能力强,适应性广,综合表现较好,适宜在四川平坝、丘陵地区种植。利用含有热带种质的优良玉米地方种质与PB类自交系进行杂交重组选育的自交系具有很高的一般高配合力和较强的适应性,组配的杂交种产量高,品质好,适应性广,具有广阔的推广应用前景。

| Abstract: | Considering the ecological environment of Sichuan area,an experiment was conducted to breed new corn varieties with high yield,high quality,multi resistance and wide adaptability.According to the principle of gene recombination,the authors combined the local tropical germplasm with PB germplasm,which was rich in disease-resistant,lodging-resistant and drought-tolerant genes,and the integration was used as the innovative strategy for breeding.Inbred-line 'LSC 107' was successfully bred and the new corn hybrid 'Wan-de No.1'was bred by crossing 'LSC 107' with 'Yi 99-19'.The results showed that the corn hybrid had good performance,including high yield,good stability,high quality,excellent disease resistance and lodging resistance,and wide adaptation.So it was adaptable for planting in plain and hilly areas of Sichuan Province.With hybrid recombination between local tropical germplasm and PB inbred lines,the inbred-line had high general combining ability and strong adaptability,and the hybrid had high yield,high quality and wide adaptability,and had broad prospects of popularization and application. |
