Combining ability and gene action for bacterial wilt disease resistance in wild tomato (Solanum pimpinellifolium) and cultivated tomato (Solanum lycopersicum) genotypes

Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive and widespread diseases of tomato in Kenya. The objective of this study was to determine the combining ability effects and gene action conditioning bacterial wilt disease resistance in tomato. Eight parents were crossed in North Carolina II mating design scheme to produce sixteen F1 hybrids. The F1 hybrids and the parental genotypes were...

Identification of drought tolerant finger millet (Eleusine coracana) lines based on morpho-physiological characteristics and grain yield

Drought stress contributes significantly to economic yield losses in finger millet (Eleusine coracana) production. This study evaluated morpho-physiological and agronomic traits among 25 finger millet genotypes for drought tolerance under field conditions. Out of the 25 genotypes, 24 were advanced lines preselected for drought tolerance from ICRISAT, KALRO and Egerton University seed units and one check cultivar P-224....
