国家种质库自1987年起开始进行花生种子的长期贮藏,截止1990年底已贮存4160份花生种质资源,其中包括栽培种4120份,野生种40份。栽培种包括多粒型、珍珠豆型、龙生型、普通型以及在品种选育过程中通过杂交育种形成的其它类型(或称中间型)等共5个类型。由于花生种子含脂肪量高,果壳疏松,种子较大,常温下极易丧失生活力。如何有效地使花生种子在长期贮存中尽可能保持其高的活力,则是关系到花生种质资源安全贮藏的关键问题。国内曾有报道不同贮藏方式对花生种子生活力的研究,但其年限短,贮藏条件也不同于国家种质库。国家库历经5年,对不
The National Germplasm Bank has been carrying out long-term storage of peanut seeds since 1987 and has stored 4,600 peanut germplasm resources by the end of 1990, including 4120 cultivated species and 40 wild species. Cultivars include a total of five types of grain type, pearl bean type, dragon type, common type and other types (or intermediate type) formed by cross breeding during breed breeding. Due to the high fat content of peanut seeds, loose shell, large seeds, easy to lose vitality at room temperature. How to effectively keep peanut seeds as high as possible in long-term storage is a key issue that relates to the safe storage of peanut germplasm resources. China has reported different storage methods of peanut seed viability research, but its short life span, storage conditions are different from the national gene pool. National library after 5 years, no
