【摘要】 忻玉6002是山西省农业科学院玉米研究所以自选系t14-3b为母本,自选系忻9101-1为父本,于2004年选育而成。在2006年山西省预备试验中,以10 984.5 kg/hm2的单产水平排第12位,比对照品种农大108增产19.0%。2007—2008年山西省区域试验(2年)中,平均产量为10 825.5 kg/hm2,比对照品种增产6.7%,位于参试品种的第8位。在2008年的玉米中晚熟组生产试验中,平均产量为10 831.5 kg/hm2,比对照品种郑单958增产6.9%,位于参试品种的第11位。该品种高产、优质、多抗,淀粉含量74.49%,属于高淀粉品种;抗玉米穗腐病(病级3)、粗缩病(病株率2.9%~4.4%),中抗玉米大斑病(病级5)、茎腐病(病株率13.8%~29.0%),感玉米丝黑穗病(病株率3.6%~17.8%)、矮花叶病(病情指数15.4~59.1);适应性广、综合农艺性状优良,平均产量可达10 880.5 kg/hm2,开发应用前景乐观。更多还原

【Abstract】 Hybrid maize variety Xinyu 6002 was bred with t14-3b as female parent and Xin 9101-1 as male parent by the Maize Institute of Shanxi Academy of Agricultural Sciences in the 2004.The results of the preliminary test in Shanxi province in 2006 showed that the average yield was 10 984.5 kg/hm2,increasing by 19.0% compared with the control Nongda 108 and ranking No.12 among all the tested varieties.In the extending trials in 2007—2008,the average yield was10 825.5 kg/hm2,increasing by 6.7% compared with the control and ranking No.8 among all the tested varieties.In the growing trials of the middle or late mature corn variety group in 2008,the average yield was 1 0831.5 kg/hm2,increasing by 6.9% compared with Zhengdan958 and ranking No.11 among all the tested varieties.This variety had the characteristics of high yield,high quality and multiple resistances and 74.49% of the starch contents.It had a strong resistance to maize ear rot(disease grade 3),rough dwarf disease(incidence 2.9%~4.4%);middle resistance to exserohilum turcicum(disease grade 5) and stem rot disease(incidence 13.8%~29.0%);sense of maize head smut(incidence 3.6%~17.8%) and dwarf mosaic virus(the disease index of 15.4~59.1).It could adapt to various soil environment and had broad agronomic traits.Generally the yield was 10 880.5 kg/hm2.The application prospects of Xinyu 6002 was good.更多还原
