由10个栽培品种和一个二倍体野生种A.Chacoenoe(Pl276235)杂交产生了三倍体的种间杂种。杂种表现了不同的交叉频率,这证明不同的花生品种的染色体配对能力是不同的,同时也揭示出克服杂交不亲合性并使之成功的可能性。为了进行普通细胞学研究并详细地鉴别外加系和替换系,对花生粗线期20条染色体进行了鉴别,并作了首次的叙述与分类。发现A—染色体是一个相当小的完全异染色质的染色体。 为了填补某些种的种子败育我们知识上的缺口,对根茎区系一些种的胚胎学进行了研究,这些种受精作用进行迟缓和不完全受精。种子败育大概是由于胚乳发育停止和内种皮细胞发育增生等原因所致。种间三倍体杂交呈现了不能受精的无配子生殖所具有的那种胚胎特征。
Triploid interspecific hybrids were generated from crossbreeding of 10Chacoenoe (Pl 276235) with one diploid wild species. Hybrids exhibit different crossover frequencies, which demonstrates that different peanut varieties differ in their chromosomal pairing ability, while also revealing the possibility of overcoming hybridization incompatibility and making it successful. In order to carry out general cytological studies and to identify in vitro lines and substitution lines in detail, twenty lines of peanut pachytene were identified and first described and classified. The A-chromosome was found to be a fairly small, completely heterochromatic chromosome. To fill some of our knowledge gaps with seeds of some species, embryoology of some species in the rhizome region has been studied, and these fertilizations have been slow and incompletely fertilized. Seed abortion is probably due to the endosperm development and the endocarp cell growth and development and other reasons. Interspecific triploid hybridization presents the embryo trait of the non-fertilized apogamy.
