【 摘 要 】

Viability of seeds in-shell of 198 cultivars of groundnut (Arachis hypogaea L.) stored at ambient temperature (5.5- 27.2°C, monthly mean for 1961-1990) since 1964, was examined in 1986, 1992 and 1993. Fifty to 100 air-dried pods of each cultivar were packed in kraft paper- or cheesecloth-bags, and 16-20 kg of them, were stored in a semi-hermetic tin-can (capacity 144 L) until 1972 and in a plastic hermetic container (75 L) after 1973, together with 5 and 2 kg calcium oxide cakes as desiccant (renewed once a year), respectively. In the two types of containers, relative humidity was 23 and 14%, respectively, and seed moisture was about 6 and 3%, respectively. Thirteen Spanish cultivars, two Virginia cultivars, and one inter-subspecific hybrid cultivar retained high germinability (&lsaquo80%) for 15-28 years of storage. Further studies on the reason of long seed viability of these cultivars, especially Spanish cultivars, and on the role of shell in retaining viability for a long period are necessary. Storage under the above conditions at ambient temperatures would be feasible as a small-scale conservation method of groundnut germplasm,especially that of Spanish cultivars, in the temperate and tropical regions.
