tailieunhanh - Mapping of quantitative trait loci (QTLS) associated with sugarcane aphids resistance in recombinant inbreed population of sorghum [Sorghum bicolor (L.) Moench]

Mapping of QTL associated with sorghum aphid resistance was undertaken in a recombinant inbred population derived from 296B (susceptible) x IS 18551 (Resistance) parents. Totally 2 QTLs spread across linkage group were detected at threshold LOD of . The alleles of IS 18551 contributed to increase aphid tolerance. QTL analysis across season revealed that QTL mapped on LG ‘J’ was a major one, explaining of the observed phenotypic variance with a peak LOD value and showed nonsignificant Q x E interaction. This major QTL flanked by two linked markers . Xtxp 15 - Xtxp 283 and it will be targeted for marker-assisted selection in a practical breeding program aiming at increasing the level of resistance in agronomically elite backgrounds through gene pyramiding for aphid resistance. | Mapping of quantitative trait loci (QTLS) associated with sugarcane aphids resistance in recombinant inbreed population of sorghum [Sorghum bicolor (L.)
