利用西欧马铃薯资源选育油炸专用型品种

Selection of deep fry potato variety using Western Europe germplasm

我国马铃薯油炸专用型品种匮乏,生产种植品种主要是大西洋和夏坡地。利用西欧种质资源配制组合,探讨选育适合黑龙江省农业生态条件油炸专用型马铃薯品种可能性。被测试无性系12个,以炸片品种大西洋和炸条品种夏坡地为对照,在哈尔滨和讷河两点评价被测无性系产量和油炸品质表现。JT04-7-23适合薯条加工,该无性系薯块长形,总产量、商品薯产量、比重与炸条品种夏坡地相当,但炸条颜色优于夏坡地。T11-197-1适合炸薯片,块茎圆形,总产量和商品薯产量略高于对照大西洋,比重和炸片颜色略逊大西洋,但仍在可接受范围内。还选出T10-6-14和N10-4018,可用作油炸品种亲本。试验结果表明,利用西欧马铃薯种质资源可选育适合黑龙江农业生态条件的油炸马铃薯品种。

There are just a few deep fry potato varieties available in China and the dominant ones are Atlantic and Shepody. The purpose of this experiment was to explore the possibility of selecting deep fry potato varieties suitable for planting in Heilongjiang agroecosystem using Western Europe germplasm as parents. Twelve clones were evaluated for yield and deep fry quality in Harbin and Nehe using chipper variety Atlantic and French fry variety Shepody as controls. JT04-7-23 performed well in French fry processing. It was long in tuber shape and was comparable to Shepody in total and marketable yield and specific gravity, but the fry color was superior to the control. T11-197-1 was suitable for chip processing. Its tuber was oval, total, and marketable yield was slightly higher than the chipper control variety Atlantic although the specific gravity and fry color was lower but still in the acceptable range. In addition, T10-6-14 and N10-4018 were selected, which could be used as parents for further improvement. The results in this experiment indicated that it was possible to select deep fry potato varieties suitable for planting in Heilongjiang agroecosystem using Western Europe gemplasm as parents.
