"Genetic mapping and quantitative trait locus analysis of resistance to sterility\r\nmosaic disease in pigeonpea [Cajanus cajan (L.) Millsp.]"^^ . "Sterility mosaic disease (SMD), considered as the “green plague of pigeonpea” and caused by pigeonpea\r\nsterility mosaic virus (PPSMV) is one of the major biotic factors, which leads to heavy yield losses\r\nand hence poses a big challenge for pigeonpea production in the Indian subcontinent. Variability in the\r\nsterility mosaic pathogen revealed the occurrence of five different isolates in India. Among them, three\r\ndistinct SMD isolates have been characterized, viz., Patancheru, Bangalore and Coimbatore. Molecular\r\ntools offer a viable option to tackle these biotic stresses via identification of the genomic regions associated\r\nwith the trait such as SMD resistance. With an aim of identifying the gene(s)/QTLs linked with SMD\r\nresistance, two F2 populations, i.e. ICP 8863×ICPL 20097 (segregating for Patancheru SMD isolate) and\r\nTTB 7×ICP 7035 (segregating for both Patancheru and Bangalore SMD isolates) were developed and F2:3\r\nfamilies were phenotyped for resistance to respective isolate(s) of SMD. After screening over 3000 SSR\r\nmarkers on parental genotypes of each mapping population, intra-specific genetic maps comprising of\r\n11 linkage groups and 120 and 78 SSR loci were developed for ICP 8863×ICPL 20097 and TTB 7×ICP\r\n7035 populations, respectively. Composite interval mapping (CIM) based QTL analysis by using genetic\r\nmapping and phenotyping data provided four QTLs for Patancheru SMD isolate and two QTLs for Bangalore\r\nSMD isolate. Identification of different QTLs for resistance to Patancheru and Bangalore SMD isolates\r\nis an indication of involvement of different genes conferring the resistance to these two SMD isolates.\r\nOne QTL namely qSMD4 identified within an interval of 2.8cM on LG 7 explaining 24.72% of phenotypic\r\nvariance, once it is validated in other genetic background, seems to be a promising QTL for use in marker\r\nassisted selection. In summary, this is the first study on development of intra-specific genetic maps and\r\nidentification of QTLs for SMD resistance in pigeonpea"^^ . "2011" . . "123" . . "Elsevier"^^ . . .
