A field trial was conducted in two localities of the Ecuadorian Andes to evaluate potato (Solanum tuberosum c.v. INIAP - Fripapa) response to inoculation with four commercial products containing the arbuscular mycorrhizal fungus (AMF) strain Rhizophagus irregularis DAOM 197198. In parallel, potat...

This protocol describes how to produce yam (Dioscorea) seeds through controlled pollination of flowers on female plants. Pollination by flower thrips takes place naturally in normal yam-growing environments in the presence of flowering male and female genotypes, although it is not efficient. This...

Twenty-two genotypes of D. rotundata cultivar Dorban consisting of 19 botanically developed seeds and 3 vegetative checks were evaluated in 15 environments from 2000 to 2004 using CRD to assess the effect of genotype and genotype x environment interaction on the tuber yield of 22 white yam (D. ro...

Fusarium wilt of bananas (Musa species) is caused by Fusarium oxysporum f. sp. cubense (Foc). Foc race 1 in particular affects dessert bananas in Uganda, causing >60% yield loss. This study was conducted to assess the performance of two new apple banana genotypes for bunch yield, resistance to Fo...

La papa constituye uno de los cultivos alimenticios más importantes en la agricultura familiar de la región andina del Perú. En las condiciones agroecológicas de esta región, uno de los factores más importantes que limita los niveles de producción y productividad de la papa es el clima adverso. C...
