Yield stability analysis of nine spring bread wheat genotypes in the central highlands of Ethiopia
(African Crop Science Society, 1995)
Eight promising bread wheat lines and one standard check cultivars were evaluated for grain yield performance, stability and adaptation across nine environments of the central highlands of Ethiopia. Results of the combined ...

Competitive ability of Ethiopian spring bread wheat cultivars with Avena fatua L.
(African Crop Science Society, 1995)
Competitive interactions of four spring bread wheat cultivars ( Triticum aestivum check for this species in other resources L.) with four wild oat ( Avena fatua check for this species in other resources L.) seedling densities ...

Screening of maize genotypes for low Striga Asiatica stimulant production using the Agar Gel Technique
(African Crop Science Society, 1994)
One of the best characterized mechanisms of resistance to the parasitic weed ( Striga check for this species in other resources ) is low germination stimulant exudation by host plants. Using a simple and rapid agar gel ...

Productividade de trigo (Triticum aestivum (L.) thell.) com tolerância ao alumínio tóxico no solo
(Embrapa Informação Tecnológica, 1994)
Existem afirmações de que aos genes de tolerância ao alumínio (Al) deviam estar ligados genes que limitariam o potencial de rendimento do trigo. Essas afirmações eram baseadas nos resultados de programas de melhoramento ...

Pathogenicity variations of Puccinia recondita f. sp. tritici and P. graminis f. sp. tritici in wheat growing areas of Mexico during 1988 and 1989
(American Phytopathological Society (APS), 1991)
A survey of Puccinia recondita f. sp. tritici in Mexico during 1988 and 1989 indicated the presence of 23 pathotypes. In the Pacific region and Highland Plateau, pathotype TCB/TD predominated both years, followed by TBD/TM. ...

Comparison of methods for inoculation of ears and stalks of maize with Fusarium moniliforme
(American Phytopathological Society (APS), 1990)
Over four plantings from 1986 to 1988, several ear- and stalk-inoculation methods for Fusarium moniliforme were compared on maize (Zea mays). Significant differences were observed among methods in their effect on disease ...

Cluster analysis, an approach to sampling variability in maize accessions
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 1996)
Cluster analysis is frequently used to classify maize (Zen mays L.) accessions and can be used by breeders and geneticists to identify subsets of accessions which have potential utility for specific breeding or genetic ...

Improvement of durum wheat yield and associated effects on morpho-physiological characters
(African Crop Science Society, 1995)
Six durum wheat ( Triticum turgidum var. durum check for this species in other resources ) cultivars released in the central highlands of Ethiopia from 1967 to 1992, were evaluated to estimate progress in improving grain ...

Improvement in yield of bread wheat cultivars released in Ethiopia from 1949 to 1987
(African Crop Science Society, 1995)
Thirteen bread wheat ( Triticum aestivum check for this species in other resources L.) cultivars popular in the highlands of Ethiopia and representative of the period from 1949 to 1987 were studied for two cropping seasons ...
