摘　　要：[目的]为经济有效地生产脱毒马铃薯原原种和提高原种繁殖量提供参考。[方法]对马铃薯新品种会-2脱毒原原种大小与原种产量及主要经济性状的相关性进行研究。[结果]脱毒马铃薯原种产量与原原种的大小存在着明显的相关关系,原种产量有随着原原种粒重的增加逐渐升高的趋势,同时,在每窝粒数、平均粒重、大中薯率3个经济性状上也存在相同趋势。原原种粒重5.0 g以上的原种产量之间的差异不显著,但与5.0 g以下的产量差异极显著;原原种粒重2.04.0 g的原种产量差异不显著,但与原原种粒重0.5和1.0g的差异极显著,说明1.05.0 g是原原种粒重经济有效的控制区间。[结论]马铃薯新品种会-2原原种的大小应控制在1.05.0 g。[Objective] The reference for the low-cost multiplication of the breeder and original virus-free potato variety was provided.[Method] The relationship between the multiplication yield of new virus-free original potato variety： Hui-2 and the size of its breeder’s variety was researched.[Result] There was a clear correlation between the multiplication yield of new virus-free original potato variety virus-free potato seed production and the size of its breeder’s variety.With the increment of single potato of breeder’s variety its multiplication yield was gradually increased.And also there was same trend in three agronomic characters： the number of breeder’s potato per hole,the average weight of breeder’s potato and the rate of size of lager breeder’s potato,as the size of single breeder’s potato.There was no significant difference between the multiplication yield of new virus-free original potato variety virus-free potato seed production and the size of its breeder’s variety when the weight of breeder’s variety potato was more than 5.0 g/each and the significant difference when the weight of breeder’s variety potato was less than 5.0 g/each.There was no significant difference between the multiplication yield of new virus-free original potato variety virus-free potato seed production and the size of its breeder’s variety when the weight of breeder’s variety potato was in the range of 2.0-4.0 g/each and significant difference when the weight of breeder’s variety potato was 1.0g/each or 5.0 g/each.It was indicated that the breeder’s variety potato the effective weight of breeder’s variety potato should be controlled in the range from 1.0-5.0 g/each.[Conclusion] The weight of breeder’s variety potato should be in the range from 1.0-5.0 g/each.
