以辣椒属(Capsicum)的7个种(包括4个变种、3个类型)计172个品种为试材,于成株期取功能叶片进行制样分析,得出过氧化物酶(POD)同工酶的基本酶谱为12条酶带,并将172份材料中各个种、类型出现的过氧化物酶同工酶表型频率用模糊聚类分析(fuzzy clusber analysis)方法进行动态聚类.结果表明,C.annuum的两个变种关系极近;C.baccatum的两个变种关系也很近; C.chi-nense与C.frutescens关系较近,这两个种及C.praetermissum与C.annuum关系亦较近,而C.annuum与C.baccatum、eximium C.chacoense关系则较远.从而得出,普通栽培辣椒,首先应该利用其野生种C.annuum var.annuum的有用基因,其次是C.frutescens、C.chinense及C.praetermissum,最后才应当考虑利用C.eximium、C.baccatum及C.chacoense的有用基因.据此对辣椒属的起源、分类及上述种质材料在育种上的应用问题进行了讨论.
172 cultivars of 7 species (including 4 varieties and 3 types) of Capsicum were taken as test materials, and functional leaves were taken at adult stage to make sample analysis. The results showed that peroxidase (POD) The basic enzyme spectrum of enzyme was 12 bands, and the peroxidase isoenzyme phenotype frequency of each species and type in 172 materials was clustered dynamically by fuzzy clustering analysis. The results showed that the two varieties of C.annuum are closely related; the two varieties of C.baccatum are also closely related; C.chi-nense is closely related to C.frutescens, these two species and C.praetermissum and C. annuum relationship is also closer, but C.annuum and C.baccatum, eximium C.chacoense farther.Therefore, the ordinary cultivation of pepper, you should first use its wild C.annuum var.annuum useful genes, followed by C.frutescens, C.chinense and C.praetermissum.Finally, we should consider the use of the useful genes of C.eximium, C.baccatum and C.chacoense.According to this, the origin, classification and the above germplasm of Capsicum Application issues are discussed.
