马铃薯杂交组合后代加工相关品质性状的评价

以马铃薯品种大西洋和东农303为母本的6个杂交组合的无性一代为试验材料,对其产量和加工相关品质性状进行评价。结果表明:综合表现最好的组合为大西洋×T1800,该组合产量高,平均单株产量可达604g;单薯重较高,平均单薯重可达80 g;高淀粉、低还原糖个体较多,后代中符合油炸加工类型的无性系比率最高。以东农303为母本的3个杂交组合后代比重偏低,但平均单株产量和平均单薯重均较高,可从这3个组合后代中筛选出高产鲜食的材料。

Evaluation for Processing Quality of Progenies Derived from Some Potato Crosses

The performance of processing quality,yield and yield components were evaluated for 6 crosses using cvs.Atlantic and Dongnong 303 as female parents in the first clonal generation.Overall,the cross of Atlantic × T1800 performed well,with high total yield being 604 g per plant and high mean tuber weight 80 g.There were lots of clones high in starch content and low in reduced sugar content in this cross,meeting the requirement for processing,especially chips.Three crosses from the crosses using Dongnong 303 as female parent had low specific gravity,but high tuber yield per plant and mean tuber weight,and therefore,selection could be made from these crosses for tablestock.
