花生栽培种,认为有两个性状各异的亚种,即密枝亚种(ssp hypogaea)和疏枝亚种(ssp fastigiata)(Gregory,1968).前者包括弗吉尼亚类型,而后者又分为两个变种:珠豆变种(Vulgaris)(西班牙类型);和疏枝变种(fastigiata)(瓦棱西亚类型).西班牙类型只有丛生型,而弗吉尼亚和瓦棱西亚类型包括 丛生和匍匐两种类型。西班牙类型在印度广为栽培,而弗吉尼亚类型在美国广为栽培。种质搜集的利用,取决于对可利用的遗传多样性的了解及其范围。有关花生变异性的报导,多限于营养体方面,而在荚果性状方面则属有限。本文对某些荚果和种子性状的多样性以及至开花的日数作了研究.
Peanut cultivars are considered to have two subspecies of different traits, namely ssp hypogaea and ssp fastigiata (Gregory, 1968). The former includes the Virginia type, which is subdivided into two Variants: Vulgaris (Spanish type); and Fastigiata (Validea type) Spanish type is only clustered, while Virginia and Valaisier types include both tufted and creeping. Spanish type is widely cultivated in India, while the Virginia type is widely cultivated in the United States. The use of germplasm collection depends on the understanding of the available genetic diversity and its scope. Reports of peanut variability are mostly limited to vegetative aspects, but limited in terms of pod traits. The paper studies the diversity of some pod and seed traits and the number of days until flowering.
