Sugarcane variety development programmes primarily envisage breeding of varieties with high cane yields and high sugar content in specific environmental conditions. Key components associated with sugar yields are tonnes of cane per hectare and sucrose content. A study was undertaken to evaluate 22 introduced sugarcane genotypes with three checks (KEN 83-737, EAK73-335 and D8484) for sucrose content in western Kenya. The... Read more.

Cowpea is an important source of food and income for small scale farmers in Uganda. Production is, however, affected by both biotic and abiotic stresses. Drought stress has recently emerged as a serious concern due to the effects of climate change. This study was therefore undertaken to estimate the general and specific combining ability effects of parents and crosses as well as estimate the heritability of delayed leaf... Read more.

Flowering in cassava is related to branching. Erect plant architecture is usually preferred by farmers but results in late and scarce flowering, which slows down breeding and genetic studies. The objective of this study was to induce earlier and more abundant flowering, which have become key research needs for cassava. Six non- or late-flowering genotypes were selected for grafting on a profuse, early flowering... Read more.

A better approach to assess plant genetic diversity is the agro-morphological characterization. The main objective of this study was to investigate the morphological variability of 87 maize (Zea mays L.) accessions collected in different agro-ecological zones of southern Benin. Thus, 16 agro-morphological characters (seven quantitative and nine qualitative) were selected from the maize descriptors. The experimental... Read more.

Molecular-assisted backcrossing (MABC) was used to introgress drought tolerance, Striga and root-knot nematode resistance QTLs into a farmer-preferred widely grown cowpea landrace adapted for intercropping in Burkina Faso. Two backcross populations were developed using two drought tolerant donor lines IT93K-503-1 (nematode resistant) and IT97K-499-35 (Striga resistant) and the drought sensitive landrace Moussa Local as...

An 8 x 8 diallel cross mating design with the parents and F1s was used to estimate gene action and combining ability for yield and yield characters in sesame (Sesamum indicum L.). The experiment was conducted at the National Semi-Arid Resources Research Institute (NaSARRI), Serere, Uganda during the second season of 2013. The traits involved: days to 50% flowering, days to maturity, height to first branch, height to... Read more.

Heritability is a basic genetic parameter for quantitative traits that may determine their selection generation and intensity as well as predict their selection response and efficiency in plant breeding. Estimation of heritability varies based on experimental design. The type 2 modified augmented design (MAD2) as an unbalanced experimental design, has been proposed for evaluating numerous unreplicated test genotypes... Read more.

The performance of cocoyam (Colocasia esculenta L. Schott) to varying levels of cow dung and potassium fertilizer was investigated in 2012 and 2013 cropping seasons under field conditions at National Horticultural Research Institute (NIHORT), Imo State, Nigeria. The experiment was a 4 × 2 factorial arrangement in a randomized complete block design with three replications. The treatments were four levels of cow... Read more.

Thirty-two faba bean genotypes were evaluated for their yield and yield components in verstisol areas of Hashenge and Aiba in 2015. Alpha lattice design with two replications was used for the experiment. The Analysis of Variance showed highly significant differences (P<0.01) for thousand seed weight over locations. Based on this, genotype EH 06007-2 scored highest 1000 seed weight (1111 g) followed by EH 06088-6... Read more.

Allelopathic potential of Citharexylum spinosum L. (Verbenaceae) an exotic tree introduced in Tunisia many years ago was evaluated. Organic extracts using hexane, ethyl acetate and methanol solvents together with aqueous extracts at different concentrations were prepared from different parts of the plant (roots, stems, leaves and flowers). Yields in the 12 organic extracts together with their phenol contents were... Read more.

Two PCR-fingerprinting primers, (GACA)4 and M13, were tested across 22 pathotypes of Puccinia hordei Otth collected from Australasia over a 30 year period, to assess their usefulness in revealing genetic variability in this pathogen. Both primers revealed polymorphisms among the pathotypes, with (GACA)4 generating a higher level of polymorphism. Molecular analyses revealed evidence of clonality among the P. hordei... Read more.

Tomato is one of the most important vegetable in Ethiopia as well as in the world in irrigated regions. It can be produced in a wide range of climatic conditions and many types of soils. Borana zone has potential to produce the crop, but not well done due to technical (production technology) and socio-economic problems. Among technical problem unavailability of seeds of adapted and improved tomato varieties is the most... Read more.
