| identification and validation of qtls conferring resistance to sorghum downy mildew (peronosclerospora sorghi) and rajasthan downy mildew (p. heteropogoni) in maize. | we have mapped the quantitative trait loci (qtls) conferring resistance to sorghum downy mildew (peronosclerospora sorghi; sdm) and rajasthan downy mildew (p. heteropogoni; rdm), two species of dm prevalent throughout india. qtl mapping was carried out on a backcross population of 151 individuals derived from a cross between cm139 (susceptible parent) and nai116 (highly resistant to both sdm and rdm). heritability estimates were 0.74 for sdm and 0.67 for rdm. composite interval mapping combined ... | 2005 | 15841363 |
