摘要:

菜豆(Phaseolus vulgaris L.)作为重要的经济作物被广泛种植,具有品种繁多、表型差异明显和基因组小的特点,是研究豆类植物基因组功能的重要材料。为了创造更多的变异材料来改良品种和丰富突变体库,以及为将来功能基因组学研究积累材料,用甲基磺酸乙酯(EMS)处理A18-1菜豆干种子,处理浓度为0.04 mol/L,对2128份M2单株在整个生长时期进行田间表型筛选,共筛选出107株突变株,占整个筛选群体的5.03%。构建了包括叶、茎、花、荚、株型、育性和熟期等性状变异的突变体,其中叶形叶色相关的突变体数量和类型都为最多,占总突变体数量的27.0%,茎和花及其育性相关的突变体数量相等且均最少,占总突变体数量的10.3%。本试验为构建和创新突变体库提供了新材料,对研究基因组功能和表型之间特异性关系及遗传育种有重要意义。

Abstract:

Kidney bean (Phaseolus vulgaris L.) as an important economic crop is widely planted. It is characterized by many varieties, obvious phenotypic differences and small genome, and has become an important material for studying the genome function of legume plants. In order to create more mutant materials for improving the varieties and enriching the mutant library, and to accumulate the materials for study genome function of legume plants in the future, dried kidney bean seeds of A18-1 were treated with 0.04 mol/L ethyl methanesulfonate (EMS), 2128 M2 plants were conducted with field phenotype selection during the whole growth period, and 107 mutants were screened, which accounted for 5.03% of the total population. The mutants were constructed with trait variations on leaf, stem, flower, pod, plant type, fertility and maturity. Among them, the number and the type of mutants related to leaf shape and leaf color were the most, accounted for 27.0%. But the number of mutants related to stems, flowers and fertility was equal and the least, taking up 10.3% of total mutants. This experiment could provide new materials for constructing and innovating mutant libraries, and it is of great significance for studying specific relationship between genome function and phenotype as well as genetic breeding.

Key words: kidney bean, ethyl methanesulfonate (EMS), mutagenesis, mutant library, phenotypic screening
