马铃薯种子的贮存寿命是育种过程中十分关注的问题。加拿大曾在1958～1978年间研究过101个组合的杂种种子。在12～15℃的培养皿中进行催芽,头5～6天有70～80％的种子萌发,经过10天又有15～25％的种子萌发。贮藏10年以后种子的萌发势与萌发力明显降低。但是,大多数样品的种子在贮藏15年甚至20年以后,仍有良好的发芽率。英国剑桥植物育种研究所曾比较于1954年授粉所 The storage life of potato seeds is a matter of great concern in the breeding process. Canada had studied 101 combinations of hybrid seeds between 1958 and 1978. Germination was carried out in a Petri dish at 12-15 ° C with 70-80% seed germination in the first 5-6 days and another 15-25% seed germination after 10 days. After 10 years of storage, the seed germination potential and germination force decreased significantly. However, most samples still have good germination rates after 15 or even 20 years of storage.
