摘要
[目的]明确不同青贮玉米品种品质性状综合表现,挖掘青贮玉米优良基因源。[方法]对8份青贮玉米杂交品种的26个品质性状进行相关性分析。[结果]这些性状可以分为营养价值指标和形态构建因素两类,这两类性状间的协调统一是优质青贮玉米品种选育的最基本尺度;品种LY19具有明显的形态建成性状优势,而品种16X259具有突出的营养价值性状优势。[结论]品种16X259在营养价值性状和形态建成性状之间达到了较好平衡,为优质饲料;营养价值性状和形态建成性状可作为优势基因源加以创新和利用。
[Objective]To clarify the comprehensive performances of quality traits of different silage maize varieties,and to discovery the excellent gene sources of silage maizes.[Method]The correlation analysis of 26 quality traits of 8 silage maize varieties was performed.[Result]These tested traits could be divided into two categories,including nutritional value indicators and morphogenetic factors.The coordination and unification of these two types of traits were the most basic scales for selective breeding of high-quality silage maize varieties.The variety of LY19 had obvious advantages in morphogenetic traits,while the variety of 16X259 had outstanding predominance in nutritional value traits.[Conclusion]The variety of 16X259 reaches a good balance between nutritional values and morphogenetic traits,and has potential to serve as a high-quality variety for silage preparation;nutritive values and morphologic traits can be used as dominant gene sources for innovation and utilization.
