花生是地上开花,地下结果的作物。然而,1982年,印度科学家在种植的巴西花生品种“Tatu”种子繁殖区中,从2826株中发现了5株有着发育相当好的气生荚果。他们以“Tatu”为对照,按株系种植观察,发现这5个株系的气生荚果所占比例均达90％以上,而单株荚果产量和有效荚果数均与对照差异很少。其它性状,如茎色、叶片、种皮、开花和成熟期等,均与对照相似。这种气生荚果突变对加速花生育种进程有着重要意义。
Peanuts are crops that blossom on the ground and produce underground results. However, in 1982, Indian scientists found from 5,826 strains of well-developed aerial raw pods in the “Tatu” seed breeding area of the Brazilian peanut variety planted. Using “Tatu” as their control, they observed that the aerial parts of these five lines accounted for more than 90% of the aerial parts, while the pod yield and the effective pod number per plant differed little from the control. Other traits such as stem color, leaf, seed coat, flowering and maturity were similar to the control. This air pod mutation to speed up the process of peanut breeding is of great significance.
