| 摘 要： | 通过田间种植，比较了马铃薯二倍体与四倍体的长势、叶色、薯形、薯皮色、薯肉色、芽眼深浅、单株产量、单株块茎数、平均块茎重等植物学和农艺性状，并对二倍体马铃薯的花粉育性以及２ｎ花粉的频率进行了鉴定。根据单株产量、块茎数、薯形、２ｎ花粉频率等综合性状，筛选出ＤＹ１４－４－２５、ＤＹ４－３０以及Ｑ４９－１－９，为进一步开展马铃薯分解育种工作打下物质基础。

| Abstract: | In a field trial,the agronomic and botanical traits of plant vigor,leaf color,tuber shape,skin color,flesh color,eye depth,tuber yield per plant,tuber set and mean tuber weight of diploid,including diploid hybrid and dihaploid 5BXSolanum tuberosum subsp. tuberosum, were compared with those of tetraploid cultivars.Also,the pollen fertility and 2n pollen percentage of diploid potatoes were examined.On the basis of tuber yield per plant,tuber set,eye depth and 2n pollen percentage,three diploid clones,DY14425,DY430 and Q4919,were selected,which may be further evaluated for their potential value in an analytic breeding program. |
