Autor: Otoo, J. Dixon, A. Asiedu, Robert Okeke, J.E. Maroya, N. Tougnon, K. Okoli, O. Tetteh, J.P. Hahn, S.K.

Multilocational trials were conducted in several agroecological zones in West Africa to assess the magnitude of genotype x environment (G x E) interaction and to identify stable varieties which could be used in breeding programs in the region. The reaction of the varieties to major cassava diseas...

A multilocational evaluation trial comprising 18 Musa genotypes was carried out from 1991 to 1994 in three representative locations in the humid forest (Onne, Nigeria and M'Balmayo, Cameroon) and the Forest-savanna Transstion (Ibadan, Nigeria) Zones of West and Central Africa. The main objective ...

The use of ploidy manipulations in potato breeding has been successfully applied by breeders at the International Potato Center (CIP) as a tool for germplasm enhancement and for the introduction of desirable genes of wild species into the cultivated gene pool. This methodology consists in reducin...

The environment substantially affects the performance of tomato (Lycopersicon esculentum Mill.) genotypes in Latin America and the Caribbean (LAC). Therefore, stability analysis can be used to select stable, high-yielding genotypes. Nine open-pollinated and six hybrid tomato genotypes and the mos...

One of the objectives of the cassava-breeding project at CIAT is the identification of clones with special root quality characteristics. A large number of self-pollinations have been made in search of useful recessive traits. During 2006 harvests an S1 plant produced roots that stained brownish-r...

Eighty-nine ewe lambs comprising 36 Shugor, 29 Dubasi and 24 Watish sheep weaned 16 weeks following birth experienced their first oestrus at an average age of 206 days. Winter-born ewe lambs attained sexual matrurity at a lower age than those lambs, which were born during the summer. The mean val...

The current study was aimed at identifying mega‐environments in Ghana and evaluating adaptability of superior sweetpotato [Ipomoea batatas (L.) Lam.] genotypes from a targeted breeding effort. Three sets of genotypes were evaluated in multi‐environment trials (MET). Twelve sweetpotato varieties w...

Cowpea (Vigna unguiculata) is an important source of protein in Africa, but production is hindered by the parasitic plant Striga gesnerioides. Crop rotation with non-host cultivars, selected to stimulate parasite seed germination, is being used successfully to control other Striga spp. and may ha...
