辐照育种是解决粮食短缺、提高农产品质量的重要技术。本研究利用中子辐照豌豆种子获得的两个豌豆突变体的M3代进行了田间试验。研究了突变体的农艺性状与产量的关系。并对其生理生化特性和种子养分的差异进行了分析。结果表明，突变叶M1的株高、单株有效荚数和单株产量分别比对照组高45.0%、43.2%和50.9%。进一步的分析将单株产量的增加归因于分枝数的增加。突变体Leaf-M2的单株产量比对照组高7.8%，这可能与叶片叶绿素含量增加有关。由于两个突变体的形态变异，其单株产量的提高存在显著差异。两个突变体的SOD活性和MDA含量与对照均有显著差异，说明两个突变体的生理调节也发生了变化。另外，两个突变体种子的铁元素含量比对照组低约10.9%，差异显著。这些发现表明，突变体Leaf-M1和Leaf-M2具有育种价值和分子生物学研究的材料价值。

英文摘要：
Irradiation breeding is an important technique in the effort to solve food shortages and improve the quality of agricultural products. In this study, a field test was implemented on the M3 generation of two mutant pea plants gained from previous neutron radiation of pea seeds. The relationship between agronomic characteristics and yields of the mutants was investigated. Moreover, differences in physiological and biochemical properties and seed nutrients were analyzed. The results demonstrated that the plant height, effective pods per plant, and yield per plant of mutant Leaf-M1 were 45.0%, 43.2%, and 50.9% higher than those of the control group. Further analysis attributed the increase in yield per plant to the increased branching number. The yield per plant of mutant Leaf-M2 was 7.8% higher than that of the control group, which could be related with the increased chlorophyll content in the leaves. There was a significant difference between the two mutants in the increase of yield per plant owing to morphological variation between the two mutants. There were significant differences in SOD activity and MDA content between the two mutants and the control, indicating that the physiological regulation of the two mutants also changed. In addition, the iron element content of seeds of the two mutants were about 10.9% lower than in the seeds of the control group, a significant difference. These findings indicate that the mutants Leaf-M1 and Leaf-M2 have breeding value and material value for molecular biological studies.
