Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis.
The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications. Ten phenotypic characteristics were assessed: plant height, leaf length,...
متن کاملBrachiaria Grasses (Brachiaria spp.) harbor a diverse bacterial community with multiple attributes beneficial to plant growth and development
Endophytic and plant-associated bacteria were isolated from plants and rhizoplane soil of naturally grown Brachiaria grasses at International Livestock Research Institute in Nairobi, Kenya. Eighty-four bacterial strains were isolated from leaf tissues, root tissues, and rhizoplane soil on nutrient agar and 869 media. All bacterial strains were identified to the lowest possible taxonomic unit us...
متن کاملNormal microspore production after cell fusion in Brachiaria jubata (Gramineae)
Cytogenetic studies were carried out on 22 accessions of Brachiaria jubata from the Embrapa Beef Cattle Brachiaria collection. One accession was diploid (2n = 2x = 18) and the remaining 21 were tetraploid (2n = 4x = 36). Among five tetraploid accessions, a specific and constant pattern of cell fusion involving only two microsporocytes was recorded. Meiosis proceeded normally from prophase I to ...
متن کاملPromising Crop Biotechnologies for Smallholder Farmers in East Africa: Bananas and Maize
In contrast to cross-breeding, genetic transformation allows for enhancement of one trait in a variety while retaining other desirable traits or attributes. Host varieties can be hybrids bred by scientists or endemic types maintained by farmers. Varieties that are popular among farmers are those whose traits or attributes are appreciated by farmers. Inserting a gene into a host variety that is ...
متن کاملPromising Crop Biotechnologies for Smallholder Farmers in East Africa: Bananas and Maize
Uganda is among the world’s leading countries in terms of banana production and consumption. Bananas occupy the largest cultivated area among staple food crops in Uganda and are primarily grown on small subsistence farms (plots of less than 0.5 ha). In addition to being a major food staple, bananas are an important source of income, with excess production sold in local markets. Average per capi...
