Book Chapter 1991

Autor: Bueno, A.

The importance of estimating genetic parameters in cassava in order to produce superior performing cv. is highlighted. Different concepts related to phenotypic variance are discussed; variance is divided into genetic (additive, dominance, epistasis) and environmental. Of the former, additive vari...

Se destaca la importancia de la estimacion de los parametros geneticos en la yuca para producir cv. superiores. Se discuten diferentes conceptos relacionados con la varianza fenotipica, la cual se divide en genetica (genetica aditiva, dominancia, epistasis) y ambiental; de las anteriores, la vari...

This study was embarked upon to stack two key but inversely associated sweetpotato traits (dry matter and beta-carotene content) through conventional breeding methods. Thirty-seven elite sweetpotato genotypes were evaluated for both traits, and 15 parents comprising five orange-, five yellow- and...

Six Rhizobium leguminosarum bv. phaseoli strains (Ciat 151, Ciat 895, Ciat 899, CE3, H2C, Kim5s) were tested for nodule occupancy in different bean cultivars at two field sites (one fertile, one acid tropical soil) and in the greenhouse. The effects of several environmental factors such as low pH...

Chemical exclusion of predators with permethrin was used to test the effectiveness of the phytoseiid predator Amblyseius limonicus Garman and McGregor and a complex of minor predators in the biological control of tetranychid (Mononychellus spp., Tetranychus spp., and Oligonychus peruvianus McGreg...

Allometric models for dominant shade tree species and coffee plants (Coffea arabica) were developed for coffee agroforestry systems in Matagalpa, Nicaragua. The studied shade tree species were Cordia alliodora, Juglans olanchana, Inga tonduzzi and I. punctata. The models predict aboveground bioma...

Elevated atmospheric CO2 will change the requirements plants have for minerals, mainly nitrogen, altering the relationship between nutrient demand and plant growth. Here, we evaluated the interacting effects between two concentrations of CO2 (390 or 750 µL L-1) and two nitrogen (N) levels (3 mM o...

The effect of shade and fertilizer application on nutrient uptake and dry matter (DM) partitioning in cocoyam was evaluated by growing the plant under different levels of shade and fertilizer application at Forest and Horticultural Crops Research Centre, Kade, within a period of 9 months. The sha...
