泉花系列花生品种高产性状及生理特性研究

试验对泉花系列花生新品种的高产性状及生理特性等进行了研究。结果表明,供试的花生新品种均表现分枝多、结荚多、出仁率较高、单株生产力高等优良特性。泉花系列品种还表现花多且集中在花前期,叶面积系数和光合势大,叶绿素含量较高,干物质累积较快较多,叶片过氧化物酶活性和根系活力强等优良生理特性。高产育种上应把分枝多、果多、果饱、出仁率高等性状作为单株选择的主要指标。

A Preliminary Study on High-yield and Physiological Characteristics of Quanhua Series Peanut Varieties

The high-yield and physiological characteristics of Quanhua series peanut varieties were studied in this experiment.The results showed that the candidate cultivars had many good characteristics for high yield,such as many branches,good podding habit,high shelling percentage and high productivity per plant.The physiological basics on high yield resulted from blooming more and in a relatively short period,high leaf area index and photosynthetic potential,high chlorophyll content,much dry matter accumulation,strong leaf peroxidase activity and root vigor.In peanut breeding,more branches,more pods and plump pods,higher shelling percentage can be regarded as important reference indexes for high yield of single plant selection.
