Preliminary evaluation of wild bean ( <i>Phaseolus</i> spp.) germplasm for resistance to <i>Fusarium cuneirostrum</i> and <i>Fusarium oxysporum</i>

چکیده

Fusarium root rot (Fusarium cuneirostrum; FRR) and wilt oxysporum; FW) are major constraints on common bean (Phaseolus vulgaris L.) production worldwide because limited genetic resistance is available in current cultivars. Wild accessions have greater diversity than cultivated germplasm could provide novel sources of for these diseases. We screened 248 wild a greenhouse setting responses to both FRR FW recorded disease severity; was observed 21 16 accessions, respectively. Accession PI417775 the most resistant FRR, exhibiting very few symptoms, whereas PI661845 PI535441 were FW. Only MX-GT-1 PI535445 Overall, collected from Andean regions had symptoms (5.4 ± 1.28 FRR; 5.8 1.12 Middle America (4.7 1.33 4.42 1.04 FW), though highest lowest scores found American accessions.

Resistance to Meloidogyne arenaria in Arachis spp. Germplasm.

Field and greenhouse evaluations of 116 wild Arachis spp. genotypes demonstrated the presence of resistance to reproduction of the root-knot nematode Meloidogyne arenaria race 1. Resistance in greenhouse tests was based on test lines having </= 2.5% of the number of eggs per gram of roots as did the susceptible A. hypogaea cv. Tamnut 74. In field tests, resistant genotypes were identified on th...

Phenotypic and Molecular Screening of Tomato Germplasm for Resistance to Tomato Yellow Leaf Curl Virus

Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...

Evaluation of Maize Germplasm for Resistance to Aflatoxin Accumulation

Aflatoxin contamination of maize grain threatens human food and animal feed safety. Breeding for reduced grain aflatoxin accumulation is one of the best strategies presently available to lower grain aflatoxin accumulation. Previously identified sources of germplasm with reduced grain aflatoxin accumulation are excessively tall and late maturing. The objective of this research was to screen germ...
