概略

R. S. Bhat 博士

Peanut, an important food and oilseed crop, succumbs to considerable yield loss due tofungal foliar diseases like late leaf spot (LLS) and rust. In the past, though concentrated
efforts were made using conventional breeding, largely they have not been very successful
in combining disease resistance, high productivity and desirable pod and kernel featuresdue to various genetic factors. Biotechnological tools, namely markers have the potential
to complement the breeding program and address some of the genetic factors. In thisregard, considerable efforts have been made by our group to develop genomic resources
and to utilize them for breeding for LLS and rust resistance. Some of the achievements
include; 1) development of several mapping populations (RILs, ILs/AB-QTL and epiRILs), mutant resources and heterogeneous inbred family (HIF)-derived near isogeniclines (NILs), 2) development and validation of SNP, AhTE and CAPS markers throughgenome-wide analysis, 3) construction of genetic/linkage maps, consensus maps and QTLmaps, 4) large-scale mutant analysis to identify trait-specific markers, 5) validation ofQTL and markers 6) development of backcross breeding lines in TMV 2, JL 24, Dh 86
and ICGS 76 7) development of mutants from the introgression lines. Superior backcrosslines with high productivity and resistance to LLS and rust are undergoing second year
multi-location trial for variety development and commercial release.
