花生优异资源“辐狮”是用~(32)P内照射“狮选64”干种子后选育而成,具有矮生,分枝多,叶小、叶厚、叶色浓绿,株型紧凑等特点。用它作杂交亲本直接或间接选育出一批优良品种,目前,广东和南方各省大面积种植的优良品种大都与“辐狮”有亲缘关系。 经显微观察,“辐狮”与“狮选64”的染色体数均为2n=40,但在花粉母细胞减数分裂中,“辐狮”的染色体有“桥”和落后染色体,花粉有显著差异,而且能够一代代遗传。“辐狮”子叶的酯酶同工酶增加了4A、5A和16A三条酶带,减少了6A、7A两条酶带,而且8A、9A、10A酶带着色深,酶的活性增强。这是由于辐射引起的,说明“辐狮”是“狮选64”的大突变体. The excellent resource of “Peanut” “Lion” is selected from the seeds of “Lion 64” after irradiation with ~ (32) P, and has the characters of dwarfism, many branches, small leaves, thick leaves, dark green leaves, Compact and so on. It is used as a hybrid parent to directly or indirectly breed a number of fine varieties. At present, most of the fine varieties planted in large areas in Guangdong and the southern provinces are related to the “lion”. Microscopically, the chromosome numbers of “Lions” and “Lions 64” were both 2n = 40, but in the meiosis of pollen mother cells, the “Lion” chromosome had “bridge” and lagging chromosomes, Significant differences, and can be inherited from generation to generation. Esterase isozymes of “lion” cotyledons increased three bands of 4A, 5A and 16A, reduced the bands of 6A and 7A, and the color of the bands of 8A, 9A and 10A increased with enzyme activity. This is due to radiation, indicating that “lion-lion” is a large mutant of “lion-selection 64”.
