花生野生种具有抗逆性强,含油量高等特点,若能把这些有利基因转移到栽培种上来,对花生生产将起到很大作用。但是具有这些优良性状的花生野生种多是二倍体种(2n=20),与栽培种杂交只能得到不育的三倍体杂种。所以要研究利用花生野生资源,首先要解决花生染色体的加倍技术。这个问题国外已有研究和报导,国内则未见有报导。我们于1981—1982年开展了此项研究,获得了六倍体的种间杂种和同源四倍体的野生种。
Peanut wild species with strong resistance, high oil content, if these favorable genes can be transferred to the cultivated species, peanut production will play a significant role. However, the peanut wild species with these excellent traits are mostly diploid (2n = 20), and can only give sterile triploid hybrids when crossed with cultivars. Therefore, to study the use of wild peanut resources, we must first solve peanut chromosome doubling technology. This problem has been studied and reported abroad, but there are no reports in the country. We conducted this study in 1981-1982 and obtained hexaploid interspecies hybrids and autotetraploid species.
