Genotypic diversity and migration of clonal lineages of Botrytis cinerea from chickpea fields of Bangladesh inferred by microsatellite markers

Abstract

An analysis of allelic diversity at nine microsatellite loci provided an insight into the population structure of Botrytis cinerea from four fields (sampled in 2003 and 2004) that represented important regional locations for chickpea production in Bangladesh. Although three populations were limited by sample size after clone-correction, a total of 51 alleles were amplified among 146 B. cinerea isolates from Bangladesh, which revealed a high amount of within-population and overall genetic diversity (HS = 0·48 and HT = 0·54, respectively). The percentage of maximal genotypic diversity (G) ranged between populations (G = 23-40), with a total of 69 haplotypes detected (G = 25). Bayesian cluster ..
