[图书][B] Relationships and utilization of Arachis germplasm in peanut improvement
SR Milla - 2003 - search.proquest.com
Cultivated peanut, Arachis hypogaea L., is a tetraploid (2n= 4x= 40) species considered to
be of allopolyploid origin. Its closest relatives are the diploid (2 n= 2x= 20) species included
with it in section Arachis. An understanding of taxonomic relationships among those species
may allow for more efficient utilization of alien germplasm in applied peanut improvement. A
total of 108 accessions, representing 26 species in section Arachis were genotyped with
AFLP markers. Cluster and principal component analyses of the data supported previous …
