Stability for descriptors of Solanum aethiopicum Shum group (family Solanaceae)

Solanum aethiopicum Shum group is a nutrient-rich and income-generating crop enterprise in various sub-Saharan Africa countries. Despite its importance, the development of its improved varieties has not been prioritized. Until now, no field-based descriptor development reference for the crop is available for testing candidate varieties for distinctiveness, uniformity and stability. The purpose of this study is to...

Inheritance and combining ability of cowpea resistance to bruchid (Callosobruchus maculatus F.)

The bruchid, Callosobruchus maculatus (F.) is one of the most destructive pests and causes substantial losses to cowpea during storage in tropical and subtropical regions. The development of successful breeding strategy requires knowledge on gene action and trait inheritance in local and improved sources. In this study, the mode of inheritance, the types of gene action and maternal effects of cowpea resistance to...

Inheritance and combing ability in maize using a 7x7 diallel cross

Twenty one F1s produced from 7x7 diallel mating along with the 7 parents were evaluated to notice the inheritance and combining ability of different traits to obtain high heterotic crosses. Genetic analysis and combing ability were analyzed following Hayman’s and Griffing’s diallel analyses, respectively. Hybrids projecting positive or negative potency ratio with >1.0 value for those traits is also the...

Genotype by environment interaction and stability analysis of cowpea [Vigna unguiculata (L.) Walp] genotypes for yield in Ethiopia

Ethiopia is claimed to be a center of diversity for cowpea production. The crop is the most drought tolerant and could help the country overcome the recurrent drought problem; however, the yield is very low due to lack of effort to develop varieties. This research was conducted to evaluate the stability of cowpea genotypes and to estimate the magnitude of genotypes by environment interaction (GEI) effect on grain yield....

Evaluations of faba bean (Vicia faba L.) varieties for yield and yield related traits in central zone of Tigray, Northern Ethiopia

A field experiment was carried out at Laelay maichew and Tahtay maichew districts in central zone of Tigray, Northern Ethiopia, for two consecutive seasons (2014/2015 to 2015/2016) under rain fed conditions. The objective of the study was to evaluate and select best performing faba bean varieties. Ten faba bean varieties including the local check were evaluated in randomized complete block design (RCBD) in three...
