Cross transferability, diversity analysis and tagging of MYMV resistance in mungbean using RGH markers

Published on May 29, 2018 03:21 AM

Mungbean and urdbean suffer from paucity of genetic
markers associated with MYMV disease. As an alternative
option RGHs were tested for transferability in 13 and 12
genotypes of mungbean and urdbean, respectively. Fiftyfive RGH markers from cowpea, chickpea and Medicago
exhibited a transferability of 58.2%, which collectively
yielded 51 alleles with an average of 1.59 alleles per locus.
PIC of individual loci ranged from 0.19 to 0.64. Phylogenetic
tree formed two different clusters of mungbean and urdbean
with six sub clusters. Two putative markers identified and
high level of transferability indicated its importance for
marker-assisted breeding.
