荷兰马铃薯新品系在大兴安岭地区的表现

2002年,从荷兰引进10个组合1 000多粒实生种籽。2003年在加格达奇种植实生苗世代,并开始选择。至2008年入选品系9个。2009年进行田间试验,以克新13号为对照,试验采用随机区组设计,评价这9个品系在大兴安岭地区的植物学性状、生育期、块茎性状、产量、商品性及其抗病性。9个品系的生育期在67～79 d之间。其中6个品系的产量高于对照,以品系22-32-20-34产量最高,折合每667 m2产量为2 751.32 kg。这些表现优良的品系可以提交参加省区域试验或作为亲本材料用于下一轮育种。

Performance of Some New Potato Clones Derived from Crosses Introduced from the Netherlands in Daxinganling

About 1000 hybrid seeds of ten crosses were introduced from the Netherlands in 2002,and grown as seedling generation in Jiagedaqi in 2003.The selection process began then,and up to 2008 nine clones were selected out.In 2009,the field trial was carried out in a randomized complete block design with cv.Kexin 13 as control to evaluate nine clones for botanical traits,growth duration,tuber characters,yield,marketable tuber percentage,and disease resistance.The growth duration for these clones ranged from 67-79 days.Six of nine clones were higher in yield than the control,with the clone 22-32-20-34 being highest,2 751.32 kg on the basis of 667 m2.These promising clones could be submitted for provincial regional trial or used as parents in a new cycle of breeding.
