随着生产的发展,我国广大花生产区迫切需要特早熟花生新品种,以解决北方地区麦油一年两熟、南方地区一年三熟和无霜期短的地区对特早熟花生品种的要求。但与特早熟有相关性的主要性状,目前国内外的报导还不多。为探讨这些关系,提高选育效果,我们从1976—1978年作了初步的观察研究。 材料与方法 供试品种(系):中早熟种花28,早熟种白沙1016,特早熟(生育期120天左右)种RH77—8,分春、夏播两组,以
With the development of production, the vast peanut production areas in our country urgently need the new peanut varieties which are very early maturing, in order to solve the problem that the peanut varieties in the northern part of China have two crops a year, three areas in the south and short frost-free areas in a year. However, the main traits associated with prematurity are not many reports at home and abroad. To explore these relationships and improve the breeding effect, we made a preliminary observation from 1976 to 1978. MATERIALS AND METHODS Test varieties (lines): P28, P10, P1076, especially early maturing (about 120 days) RH77-8, spring and summer sowing
