高产玉米杂交种晋单77选育及应用

为了选育高产、抗旱、抗倒伏、抗病玉米新品种,山西省农科院现代农业研究中心采用传统育种方法与分子技术结合,利用美国玉米优良种质,以L3115作母本,以L0367作父本选育出'晋单77号'玉米杂交种,2010年通过山西省品种审定委员会审定.'晋单77号'具有高产、优质、多抗、耐密的优点,淀粉含量74.45%,属高淀粉品种,平均产量达11400 kg/hm2.该品种的种子生产技术简便,产量高,降低了生产成本.在生产中结合科学管理,提高单产,带动总产增加,为保障粮食安全奠定基础,开发应用前景乐观.

Breeding and Application of Hybrid Maize Variety'Jindan 77'

The purpose was to breed high yield, and drought, lodging and disease resistant new maize varieties. The traditional breeding methods and molecular techniques were combined, and the excellent American maize germplasm was used,'Jindan 77'was bred with L3115 (female) and L0367 (male) in Modern Agriculture Research Centre of Shanxi Academy of Agriculture Science. The variety passed the assessment of Shanxi Crops Variety Examination Committee in 2010.'Jindan 77'had high yield, good grain quality, multi-resistance, and resistance to high density. Its starch content was 74.45%, and the average yield was 11400 kg/hm2. The hybrid seeds production technology was easy, and the yield was high, so the cost of production was reduced. The combination of production and scientific management could increase the yield per unit area and the total production of maize, thus to play a significant role in ensuring the food security in China. The application prospect of'Jindan 77'is promising.
