Phenotypic Diversity Analysis Of Mung Bean Germplasm Resources In Shanxi Province

Mung bean (Vigna radiate) has a long-term cultivation history and is one of the main food legume crops in China. It has high nutritional value, rich in protein, starch, fat, trace elements, vitamins and other nutrients and has medicinal value.which is good medicine Edible crops. Mung wide adaptability, strong resistance, with other crops irreplaceable role in restructuring the agriculture and the high-yield, high-quality, high-efficiency agriculture development.Shanxi Province is one of the main producing areas of mung beans. In recent years, the state of mung beans and other legumes are also stepping up efforts to research funding. In order to further clarify the breeding of new targets, to fully grasp the genetic diversity of the province mung bean germplasm resources, solve the narrow mung beans parental genetic background problems and create high-quality, multi-resistant, dedicated resources, the paper on the morphological level, to 180 from around the Shanxi copies of mung bean genetic diversity of resources designed to mung bean variety improvement and innovation in scientific resources to provide a theoretical basis for this pro-choice, the main findings are as follows:1.The genetic variability of mung bean germplasm resources in Shanxi larger. According to an analysis of nine diversity of major agronomic traits tested varieties showed 180 average diversity index was 1.429 mung resources, genetic diversity than the rich. In nine major agronomic traits in genetic diversity index growth days, plant height, single pod, seed weight and other six quantitative traits were significantly higher than the seed coat gloss, color, etc.3 grain quality traits, genetic diversity richer. Agronomic traits from a single point of view, a single pod and kernel weight of the highest diversity index reached 2.03, the genetic diversity than the rich. It offers a broad selection of parental resources for the cultivation of high-yielding varieties. The average population of the tested material diversity index 1.182.10 a mung bean germplasm tested the genetic diversity of populations showed differences in geographic distribution, including Jinzhong groups (33) up to 1.378 diversity index, Linfen groups (27 copies), followed by the diversity index was 1.363, followed by (32 parts Luliang groups,1.338), Taiyuan groups (14 copies,1.325), (17 parts Yangquan groups (15 parts,1.201) and Datong groups,1.188), indicating germplasm genetic diversity of these groups is rich; while genetic Shuozhou groups (four copies,0.732) and Jincheng groups (five copies,0.957) the lowest diversity index, the lowest degree of germplasm resource diversity; other two diversity of populations between them.2. Breeding parental choice in order to provide a viable approach. Due to the presence of the growth period and plant height was significantly positively correlated with pods per plant and yield per plant were significantly or very significantly negatively correlated, so you can choose early maturing varieties to achieve the indirect effect by selecting the dwarf materials, while improving yield per plant, to improve the quality of goods effect of mung bean, improve breeding efficiency.3.Cluster analysis results provide a basis for the use of resources.6 large group, the group has a group of precocious, high yield, erect characteristics, and grain are all green, can be used as selection precocious, high-yield, high-quality mung bean varieties material of choice. The first two groups of salient features are dwarf, yellow tablets, dedicated mung bean varieties to choose excellent material, also can be used as an intermediate material hybridization process. Group 5 for the precocious group, dwarf, large grain materials, morphology excellent, good commodity, is to select precocious, high-quality, large grain mung beans important material varieties. Group 6 group is in late-maturing, high bar, large grain materials, is to choose a large grain, high-yielding varieties of important materials, intermediate materials can be used as hybridization process.4.Cluster analysis results between groups from different geographical sources of mung beans and mung beans 180 Cluster Analysis results are basically consistent groups, most of the geographical and ecological environment similar resources are gathered together, so geographical location and ecological environment is the cause of mung bean germplasm one of the important reasons of genetic diversity; but there are a few exceptions, this is mainly due to the complexity and resource sharing between different geographic origin of the geographical origin of the same resources caused by human choice...
