水稻种子在一般仓库贮藏条件下,寿命仅2—3年,这给水稻育种和良种繁育工作带来一定困难,因为育种者需要保存大量原始材料。同时,在新品种育成推广以后,由于累年繁育,选种者掌握的入选条件不能完全一致,多次的繁育过程也增加机械混杂和生物学混杂的机会。因此,采用简便易行的贮藏方法延长种子寿命,不仅每年可以减少种植大量原始材料的工作量,还可以逐年提供低世代的原原种,供良种繁育的需要,提高生产用种的质量,延缓品种退化的过程。
Under normal storage conditions, rice seeds have a life expectancy of only 2-3 years, which poses some difficulties for rice breeding and breeding because breeders need to conserve a large amount of raw materials. In the meantime, after the new breed is promoted and popularized, the selection conditions mastered by the seed seer can not be completely consistent due to the year-long breeding. Multiple breedings also increase the opportunities for mechanical confounding and biological confusion. Therefore, using simple and convenient storage methods to prolong seed life can not only reduce the workload of planting a large amount of raw materials every year, but also provide the low-generation original seedlings each year for the purpose of breeding well, raise the quality of production seedings and delay Variety degradation process.
