试验目的对引进并初步鉴定表现好的15个品种进行多点鉴定评价,监测各品种在不同生态区域种植的物候期、抗逆性,对植株、穗部性状、品质、经济性状及产量进行比较分析,筛选出适宜不同生态区域种植的优质高产品种4~5个,为区域品种布局做准备。2试验设计随机区组设计,重复3次,小区长5m,宽2m,面积为10m2。区距50cm,行距30cm,每个小区种7行,密度75万/hm2左右,行留苗105株。
The objective of the experiment was to evaluate and evaluate the multi-spots of 15 cultivars which were introduced and preliminarily appraised. The phenophase and stress resistance of each cultivar in different ecological areas were monitored. The characters of plant, ear, trait and yield were compared Analyzed and screened 4 to 5 high quality and high yield varieties suitable for planting in different ecological regions to prepare for the regional variety layout. 2 Experimental design Randomized block design, repeated 3 times, cell length 5m, width 2m, an area of 10m2. A distance of 50cm, row spacing 30cm, 7 rows of each district, the density of about 750,000 / hm2, RML15 lines.
