Evaluation of alternative selection objectives and schemes for optimisation of village goat improvement programs por Bett, R.C., Okeyo Mwai, Ally, Kosgey, I.S., Kahi, A.K., Peters, Kurt J.

“…Considered were two selection schemes; within-group (WG) and across-groups (AG), and three alternative selection objectives; ALT I- defined based on relative weights (RWs) derived from producers’ preferences, ALT II- based on economic values (EVs) without risk and ALT III- based on risk-rated EVs, at different intensities of buck selection (proportion of bucks selected, P = 0.02 and 0.04) and selection criteria (mass and BLUP). The genetic gains (ΔG) in the breeding-objective traits, aggregate responses (RH), total economic response (TER) and the rate of inbreeding (ΔF) per generation varied depending on the scenarios ALT I, II and III, P and the selection criteria. …”

Breeding for resistance to bean golden mosaic virus in an interracial population of Phaseolus vulgaris L por Morales, Francisco José, Singh, Shree P.

“…Of these RILs, 11 lines did not develop any symptom, 24 lines had a mean disease incidence of 8%, 28 lines had a disease incidence of 26.6% and developed intermediate mosaic symptoms, and 20 lines were more susceptible (>50% disease incidence and severe yellowing) than either of the parents, which had 25% to 38% disease incidence and moderate symptoms. Heritability for disease incidence was 0.54±0.01, for foliar yellowing 0.36±0.13, for pods plant-1 0.69±0.01, for seeds plant-1 0.54±0.09, and for yield plant-1 0.49±0.01. …”

The plant pathogen Phytophthora andina emerged via hybridization of an unknown Phytophthora species and the Irish potato famine pathogen, P. infestans por Goss, E.M., Cárdenas, M.E., Myers, K., Forbes, G., Fry, W.E., Restrepo, S., Grunwald, N.J.

“…Hybrid plant pathogens have traditionally been difficult to detect or confirm, but the increasing ease of cloning and sequencing PCR products now makes the identification of species that consistently have genes or alleles with phylogenetically divergent origins relatively straightforward. We investigated the genetic origin of Phytophthora andina, an increasingly common pathogen of Andean crops Solanum betaceum, S. muricatum, S. quitoense, and several wild Solanum spp. …”
