晋超甜1号主要品种特性及高产制种技术

The Main Characteristics of Super Sweet Corn Jinchaotian 1 and Its High-yielding Seed Production Techniques

晋超甜1号是由山西省农业科学院玉米研究所自主选育的超甜玉米新品种,于2011年通过山西省审定,2014年通过国家审定。其母本为自选系TY37/7710,父本为自选系TY32-111。该品种具有商品品质优、高产、稳产、抗病性强等特点。该研究介绍了晋超甜1号主要特性,并从适时播种、合理密植、科学施肥、防治病虫害、优选基地、除杂去劣、人工去雄、辅助授粉、割除父本、采收入库等方面介绍了其高产制种技术。

The production technique of super sweet corn differs from that of the general corn. Its unique production technology directly affects the yield and quality of hybrid, and further influences the price, market share, the extension of cuhivars and the benefit of planting farmers. Based on the exploratory experiment in several years, the unique seed production technique was established. Jinchaotian 1 was breed by Maize Institute of Shanxi Academy of Agricultural Sciences, formally passed the validation of Shanxi Province in 2011 and national examination in 2014. Its fe- male parent and male parent were self lines TY3717710 and TY32-111, respectively. This cuhivar had the characteristics of high quality, high and stable output, strong disease resistance and so on. The main characteristics of Jinchaotian 1 were introduced, as well as the high output seed production techniques, such as suitable sowing date, rational close planting, scientific fertilizer application, insect and disease prevention, removing impurities, artificial emasculation, supplementary, pollination, and cutting out male parent.
