Resistance Mechanisms of Tomato (Solanum lycopersicum) to Root-Knot Nematodes (Meloidogyne species)
Root-knot nematodes (Meloidogyne species) are the most devastating and as such they cause significant yield loss in tomato production. They are widely distributed in major tomato producing areas especially in warm climatic conditions. Because of the environmental impact of the application of pesticides, the use of nematode resistant varieties is becoming the most effective alternative to control root-knot nematodes....
Genetic variability studies on bread wheat (Triticum aestivum L.) genotypes
Thirty bread wheat genotypes were tested to assess the genetic variability, among studied genotypes using alpha-lattice design at Tongo sub-center of Assosa Agricultural Research Center and Kulumsa Agricultural Research Center in 2015. Analysis of variance revealed that there were statistically significant differences among the genotypes for most of the traits at individual and across locations. From the combined...
Phenotype characterization and diversity assessment of mango (Mangifera indica L.) cultivars in Ethiopia
Little efforts have been made on mango genetic resource assessment in Ethiopia though it is one of the major fruit crops. This study was conducted to assess the diversity of 69 mango cultivars of different growing regions of the country based on 44 phenotypic descriptors. The results of both univariate and multivariate analysis of variance computed for quantitative data, and results from descriptive statistics for...
