花生原产于南美洲,国外从三十年代就开始研究花生野生资源的利用,到五十年代初才获得了与栽培种杂交的不育三倍体杂种,到七十年代不少国家重视了这项研究,并获得了一些抗病性强、品质优良的种间杂种材料。 国内从近几年开始研究,我们先后对花生种间杂交亲和性及花生种间三倍体杂种染色体加倍技术等进行了报导,同时也获得一些杂种材料和连续与栽培种回交的子代材料,现正在选育中。 花生种间杂交,由于双亲的染色体倍性不同,杂交后产生的三倍体(2n=30)杂种尽管经过人工加倍处理后,F_1代杂种成为可育的异源六倍体(2n=60),
Peanut originated in South America, foreign countries began to study the use of wild peanut resources from the thirties, until the early fifties and early access to the cross with sterile varieties of sterile triploid hybrids, many countries in the seventies attention In this study, some interspecific hybrids with high disease resistance and high quality were obtained. Since the beginning of recent years in China, we have reported on the compatibility of interspecific hybridization between peanut and triploid hybrids of peanut interspecific hybrids, and also obtained some hybrid materials and backcrossing generations of continuous and cultivated species Materials, are now breeding. Due to the different parents’ chromosome ploidy, the hybrid F1 hybrids (2n = 30) hybrids became fertile allogenic hexaploid (2n = 60) after hybridization. ,
