摘要
Treatment of Pisum sativum (L.) cv 'Sparkle' with ethylmethane sulfonic acid produced a stable mutant, E107, which forms few nodules. The mutant allele exhibits other pleiotropic properties including bronze necrotic spots on the leaflets and high accumulation of iron in the shoot. The mutant phenotype is under monogenic recessive control. The gene, designated brz (bronze), is nonallelic with two other genes conditioning necrotic spots on leaves of other mutants of P. sativum. The brz allele was located on chromosome 4 by linkage with wax production controlled by alleles at the was locus.
