花生属植物包括7个区组12个区系约100个种,是重要的植物资源,在维护生态平衡、保持水土、美化环境、饲养牲畜等方面有着广泛的用途,特别是在花生育种中表现了高产、优质、抗病、抗虫等有利性状。在花生育种中人们通过人工产生三倍体、双二倍体、同源四倍体和四倍体野生种×四倍体栽培种等多种途径解决花生野生种和栽培种染色体倍数不同的困难,为野生种的有利基因向栽培种转移提供了可能性。
About 100 species of peanut flora, including 12 flora and fauna in 7 groups, are important plant resources and have been widely used in ecological balance, soil and water conservation, landscaping and livestock breeding, especially in peanut breeding The high yield, high quality, disease resistance, insect resistance and other favorable traits. In peanut breeding, people have different difficulties in multiplying chromosomes of peanut wild and cultivated species by artificially producing triploid, diploid, autotetraploid and tetraploid × tetraploid cultivars , Which provided the possibility of transferring the favorable gene of wild species to cultivated species.
