Genetic Diversity of Arachis hypogaea var.hirsute in Peanut
龙生型花生的遗传多样性

Arachis hypogaea L.var.hirsute is the earliest peanut variety introduced in China.Many landraces were formed with different characteristic by natural and artificial selection.And China has gradually become one of the redeposit centers of Arachis hypogaea var.hirsute.Results of this research show that there is abundant genetic diversity in 15 landraces on basis of the systematical study on morphological character,quality character and AFLP analysis.It varies from 5.10 to 34.60 in variant coefficient and from 1.17 to 2.04 in diversity index.Furthermore,the trends of change are on the contrary between variant coefficient and diversity indices.The 15 landraces are divided into two groups by clustering analysis based on morphological and quality character at value 6.5.One group is made of landraces originated from Guangxi,and the other group from other provinces.The 15 landraces are classified into five groups by clustering analysis based on AFLP markers in value being 3.9.One group is made of landraces originated from Guangxi,and the other from other provinces.
