玉米是秦巴山区的主要粮食作物,也是最主要的饲料来源。玉米的高产稳产对当地农业的发展举足轻重,因此优质、高产、抗病、适应性强和适宜的生育期是该区育种必须考虑的重要目标,也是实现秦巴山区玉米可持续发展战略的重要举措。概述了秦巴中高山区玉米杂交种自交系及地方种质改良创新的情况等,对地方种质改良创新的对策及利用途径进行了探讨。 Maize is the main food crop in the Qinling and Palestinian mountains and is also the most important source of feed. Therefore, high quality, high yield, disease resistance, strong adaptability and suitable growth period are the important goals that must be considered in breeding in this region and also an important measure to realize the sustainable development strategy of corn in Qinling-Bashan Mountains. . In this paper, the inbred lines of maize hybrids and the improvement of local germplasm resources in Qinba high and middle mountainous areas were summarized. The countermeasures and utilization ways of improving and innovating local germplasms were discussed.
