- 摘要:
- 为扩大优良青贮玉米资源数量，推动黑龙江省青贮玉米产业及畜牧业发展，选取14个待测新品系作为试验材料，以青贮玉米品种阳光1号为对照，分析产量性状、倒伏性状、品质性状及其相关关系。结果表明：青贮玉米品系NJ01/R0818的鲜草产量、干物质产量、果穗产量较高，具有抗倒伏性，营养品质均达到国标一级标准，可作为中熟青贮玉米品种申请品种区试和审定。青贮玉米品系M476/S21鲜草产量、干物质产量、果穗产量较高，生育期适宜，淀粉、中性洗涤纤维、粗蛋白含量符合青贮品质一级国标等级，具有抗倒伏性，是表现优良的中熟粮饲兼用型青贮玉米品系。筛选出的青贮玉米自交系可有效改善黑龙江省青贮玉米种质资源短缺的现状
- Abstract:
- The aim of this research was to expand silage maize resources and promote the development of silage maize industry and animal husbandry in Heilongjiang Province,a field experiment was set up with 14 lines of silage maize and three replications in a random design,and Yangguang 1 was used as control.Total herbage dry matter yield,grain yield,quality,and lodging resistance were recorded,and relationships among agronomic characters were examined.The results showed that:the fresh matter yields,dry matter yields and yields on ears of maize of silage maize line NJ01/R0818 was higher,it can be used as a medium mature silage maize variety with better lodging resistance,nutritional quality in line with national standards.M476/S21 had higher fresh grass yield,dry matter quality and ear yield,suitable growth period,starch,neutral detergent fiber and crude protein content in line with the first-class national standard of silage quality,and had lodging resistance.It is a medium mature silage maize line with excellent performance.The selected silage maize inbred lines can effectively improve the shortage of silage maize germplasm resources in Heilongjiang Province.
