谷子是我省主要秋粮作物之一，具有营养价值高、耐旱、稳产、耐贮藏等特点．在旱作农业中占有重要地位。良种是实现高产、优质、高效的重要物质基础．据美国伊利诺斯大学报道，品种改良占各种增产因素的3O％～50％。因此，不断健全和完善谷子良种繁育体系，为生产提供遗传性稳 Millet is one of the main autumn crops in our province, with high nutritional value, drought tolerance, stable yield, storage resistance and other characteristics. In dry farming agriculture occupies an important position. Varieties are the important material basis to achieve high yield, high quality and high efficiency. According to the report of the University of Illinois, breed improvement accounted for 3O% ~ 50% of various yield factors. Therefore, we must continue to improve and perfect the millet seed breeding system and provide genetically stable production
