推广应用玉米优良杂交种是获得粮食增产的重要措施。紧凑型品种掖单13杂交种近年来引进示范后,由于增产显著,澡受农户的欢迎。该品种在今后生产应用中,具有扩大推广种植的趋势。为了满足农业生产用种,提高杂交种子繁殖系数,增加制种经济效益,我们对掖单13进行了高产制种技术模式化的研究。 1 研究内容与方法 1.1 掖单13亲本“478”、“丹340”自交系夏直播生育特点观察。通过亲本生育特点观察试验,探讨出两个亲本材料的生育特点、特征、特性、雌雄穗分化形成规律及抗病性能,为在本地配制掖单13杂交种提供可靠的父母本花期相遇最
Promote the application of hybrid corn is an important measure to increase grain yield. Compact varieties Yeda 13 hybrid introduced in recent years after the demonstration, due to significant increase in production, the bath by farmers welcome. The variety in the future production applications, with the expansion of the promotion of planting trends. In order to meet the demand of agricultural production, increase the breeding coefficient of hybrid seeds and increase the economic benefits of seed production, we conducted a study on the patterning of high-yielding seed production techniques for Yedan13. 1 Research content and methods 1.1 Yedan 13 parents “478 ”, “Dan 340 ” inbred line summer seeding characteristics of the observed. By observing and experimenting on the characteristics of parental development, the characteristics of parental development, characteristics, characteristics, differentiation and formation of male and female spikes and disease resistance were explored.
