Identification of single nucleotide polymorphism (SNP) markers closely linked with powdery mildew resistance gene Pm5e in wheat
Wheat (Triticum aestivum L.) is one of the most important food crops worldwide. Powdery mildew (Pm), caused by Blumeria graminis f. sp. tritici is a severe disease in wheat production. Gene Pm5e, from a Chinese wheat cultivar Fuzhuang 30 has proven to be a valuable resistance source for Pm in breeding. To further map this gene and develop Kompetitive allele-specific PCR (KASP) assays for marker-assisted selection (MAS),...

Genotype by environment interaction and yield stability analysis of open pollinated maize varieties using AMMI model in Afar Regional State, Ethiopia
The present study attempts to analyze the magnitude of GxE interaction and evaluates the adaptability and stability of open pollinated maize genotypes for grain yield, using AMMI (Additive Main Effects and Multiplicative Interaction) model. The field experiment was conducted for two consecutive years during the off seasons of 2016/17 and 2017/18 at three locations namely, Awra, Dalifage and Dubti. The experiment in each...

Fusarium oxysporum Race 1 resistance and quality traits variations in apple banana germplasm
Musa species, AAB genome group, commonly known as Sukali Ndizi (SND) in Uganda, has attained a substantial commercial value in the recent past owing to its superior fruit quality attributes and better prices. However, its sustainable production and productivity are highly threatened by Fusarium wilt. To facilitate large scale area expansion of this important dessert banana, the present study was carried out to identify...

Effect of low temperature stress on field performance of highland sorghum (Sorghum bicolor (L.) Moench) at flowering stages
Sorghum is a C4 grass native in the semi-arid environments of the African sub-Saharan and consequently chilling stress can affect the performance of the crop, especially at the reproductive stages. Moreover, a significant delay of flowering and maturity was observed when sorghum grows under low temperatures regions, and consequently farmers in highland areas of Uganda face yield penalties. Forty genotypes were evaluated...

Agro-morphological characterization of pigeonpea (Cajanus cajan L. Millspaugh) landraces grown in Benin: Implications for breeding and conservation
Pigeonpea (Cajanus cajan L. Millspaugh) is a neglected and under-utilized crop consumed in several regions of word. In order to assess performance of pigeonpea landraces grown in Benin for useful breeding programs, 50 accessions were collected from 39 villages. These accessions were characterized by using 12 qualitative and 11 quantitative traits. Based on the seeds morphological characteristics, the 50 accessions were...

Genetic variability, heritability and correlation of quantitative traits for Arabusta coffee (C. arabica L. X Tetraploid C. canephora Pierre)
The biennial bearing and the long productive nature of coffee makes it difficult to release coffee variety within a short time span. This study aimed at evaluating the yield performance of the Arabusta hybrids and its backcrosses developed by Coffee Research Institute of the Kenya Agricultural and Livestock Research Organization (KALRO-CRI) using the morphological traits. Nineteen coffee genotypes were evaluated at...

Variability, Association and Path Coefficient Analysis of Green Pod Yield and Yield Components of Hot pepper (Capsicum annuum L.) Landraces at Mereb Lehke, Northern Ethiopia
Understanding the genetic variability and diversity of crops is the basis for breeding and improving of crops. Sixty four Ethiopian hot pepper genotypes were evaluated in 8×8 simple lattice design for genetic variability in green fruit yield and yield related traits at Axum Agricultural Research Center during 2018/2019 under irrigation. Data were collected on green pod yield and yield related characters. The...

Evaluating natural infection of fungal, bacterial and viral pathogens to dry bean genotypes under field conditions
Fungal, bacterial and viral diseases are economic foliar diseases that cause yield losses, between 40 and 100%, in commonly grown dry bean cultivars in the world. Development of disease resistance genotypes is a complex interaction between genetic and environmental factors. This study focused on determining the natural infection of disease-causing pathogens of angular leaf spot, powdery mildew, bacterial blight and bean...
