ABSTRACT The dynamic multiline population breeding strategy integrates principles from the gene stacking and multiline approaches and allows application of the multiline strategy to cross-pollinated hybrid crops. Experiments were conducted to evaluate the effectiveness of the breeding approach. Backcross derivatives of pearl millet Tift 23DB were developed with rust resistance from 18 Burkina F...

Fusarium wilt of flax (Linum usitatissimum L.) caused by Fusarium oxysporum f. sp. lini (Fol) is an economically important disease that can result in severe yield losses. Due to the pathogen’s ability to survive in soil for long periods, it is essential to identify fusarium wilt resistant flax varieties. The objectives of the study were to phenotype and compare a recombinant inbred line (RIL) p...

BACKGROUND Sudden death syndrome (SDS) of soybean caused by Fusarium virguliforme spreads and reduces soybean yields through the North Central region of the U.S. The fungal pathogen and Heterodera glycines are difficult to manage. METHODOLOGY/PRINCIPAL FINDINGS The objective was to determine the contributions of H. glycines and F. virguliforme to SDS severity and effects on soybean yield. To ...

Turcicum Leaf Blight (TLB) is a common foliar disease of maize. The aim this study was to find quantitative trait loci (QTL) for TLB resistance in By crossing two inbred lines, CM 212 (susceptible) and 145 (resistant), mapping population developed, which evaluated environments namely E1 (Varanasi, U.P., India; 250 N, 830 E) E2 (Nagenahalli, Karnataka, 120 760 E). Data on four severity traits vi...
