研究了50份鹰嘴豆(Cicer arietinum L.)对8种野生一年生鹰嘴豆进行了评分,并用于评估遗传多样性和繁殖力。 16个酶系统共检测到22个可评分的位点,其中21个位点具有多态性。 种间变异普遍(D(st)= 0.510),但种内变异不普遍(H(s)= 0.050)。 在栽培鹰嘴豆中没有发现同工酶位点的变异。 鹰嘴豆的多态位点比例最高(0.59),Adh-2和Lap位点的多态性最高。 一年生鹰嘴豆种的等位酶数据所确定的,一般证实了那些基于其他字符在以前的研究。 鹰嘴豆Cicer arietinum、鹰嘴豆C. reticulatum和C. echinospermum和C. pinnatifidum,C. bijugum和C. judaicum形成另一个集群。 Cicerchorassanicum与C. yamashitae,而C. cuneatum形成一个独立的类群,与C.燕麦草
Allozyme variation among 50 accessions representing the cultivated chickpea (Cicer arietinum L.) and eight wild annual Cicer species was scored and used to assess genetic diversity and phylogeny. Sixteen enzyme systems revealed 22 putative and scorable loci of which 21 showed polymorphism. Variation was prevalent between species (D(st) = 0.510) but not within species (H(s) = 0.050). No variation for isozyme loci was detected in the cultivated chickpea accessions. Cicer reticulatum had the highest proportion of polymorphic loci (0.59) while the loci Adh-2 and Lap were the most polymorphic over all the species accessions. The phylogeny of annual Cicer species, as determined by allozyme data, generally corroborated those based on other characters in previous studies. Cicer arietinum, C. reticulatum and C. echinospermum formed one cluster, while C. pinnatifidum, C. bijugum and C. judaicum formed another cluster. Cicer chorassanicum was grouped with C. yamashitae, whereas C. cuneatum formed an independent group and showed the largest genetic distance from C. arietinum.
