Plant Dis . 2019 Mar; 81(2):217-221. PMID: 30870900
Accessions of Lycopersicon cheesmanii, L. chmielewskii, L. esculentum var. cerasiforme, L.hirsutum, L. parviflorum, L. peruvianum, L. pennellii, L. pimpinellifolium, and three interspecific hybrids of L. peruvianum with L. esculentum, were...

Ulloa M, Wang C, Saha S, Hutmacher R, Stelly D, Jenkins J, et al.
Genetica . 2016 Feb; 144(2):167-79. PMID: 26882892
Chromosome substitution (CS) lines in plants are a powerful genetic resource for analyzing the contribution of chromosome segments to phenotypic variance. In this study, a series of interspecific cotton (Gossypium...

Omwega C, Roberts P
Theor Appl Genet . 2013 Nov; 83(6-7):720-6. PMID: 24202746
Bean lines PI 165426, PI 165435, and Alabama no. 1, possessing resistance to Meloidogyne incognita, and bean lines A315 and A445, possessing gene Me1, were tested against several Meloidogyne incognita...

Cap G, Roberts P, Thomason I
Theor Appl Genet . 2013 Nov; 85(6-7):777-83. PMID: 24196050
The inheritance of heat-stable resistance to the root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood, was studied in crosses between different accessions and clones of Lycopersicon peruvianum L. F1, F2...

Veremis J, Roberts P
Theor Appl Genet . 2013 Oct; 93(5-6):960-7. PMID: 24162431
Lycopersicon peruvianum PI 270435 clone 2R2 and PI 126443 clone 1MH were crossed reciprocally with three L. esculentum-L. peruvianum bridge-lines. The incongruity barrier between the two plant species was overcome;...

Theor Appl Genet . 2013 Oct; 93(5-6):950-9. PMID: 24162430
Resistance to Meloidogyne incognita (Kofoid and White) Chitwood in clones of Lycopersicon peruvianum (L.) Mill. PI 126443-1MH, 270435-2R2 and 2704353MH, their F1, a field-produced F2, and their test-cross (TC1) populations,...

Theor Appl Genet . 2013 Oct; 93(5-6):894-901. PMID: 24162423
Clones of Lycopersicon peruvianum PI 2704352R2, PI 270435-3MH and PI 126443-1MH expressed novel resistance to three Mi-avirulent M. javanica isolates in greenhouse experiments. Clones from PI 126443-1MH were resistant to...

J Nematol . 2012 Jun; 42(4):352-8. PMID: 22736869
Few sources of resistance to root-knot nematodes (Meloidogyne incognita) in upland cotton (Gossypium hirsutum) have been utilized to develop resistant cultivars, making this resistance vulnerable to virulence in the pathogen...

J Nematol . 2012 Jun; 41(2):120-7. PMID: 22661784
A comprehensive survey of the plant parasitic nematodes associated with cowpea (Vigna unguiculata) production fields was carried out in the three primary agro-climatic zones of Burkina Faso in West Africa....

Xu P, Wu X, Wang B, Luo J, Liu Y, Ehlers J, et al.
Heredity (Edinb) . 2012 Mar; 109(1):34-40. PMID: 22378357
Association mapping of important traits of crop plants relies on first understanding the extent and patterns of linkage disequilibrium (LD) in the particular germplasm being investigated. We characterize here the...
