Selection for Some Economic Characters and Southern Blight Resistance in Dry Bean

“…These results are in accordance with the findings of Costa et al (2010), Wasonga et al (2010), Hamed (2012) and Hamed and Muhanna (2017) who indicated the possibility of selecting new common bean lines with high yield.…”

“…Therefore, these studied traits can be improved through selection based on phenotypic observations in early segregating generations. These results are confirmed with the findings of Nosser (2011) and Hamed and Muhanna (2017) who indicated that yield, plant length, number of pods/plant and pod length characters were influenced more by genetic than non-genetic factors and the differences between GCV and PCV were narrow with respect to genetic advance. Also, Hamed and Khalil (2010), Nosser (2011) and Hamed and Muhanna (2017) found that broad-sense heritability ranged from moderate to high for the same studied characters and suggested selection for improving these traits, meanwhile, Ejara et al (2018) indicated that the PCV values were relatively greater than GCV in magnitude for the traits seed yield and number of primary branches, but was relatively low for plant length and number of seeds per pod.…”

“…Development of high yielding cultivars with resistance to major bean diseases is an important breeding priority to reduce impact of diseases and increase common bean production. Also, Costa et al (2010), Wasonga et al (2010), Hamed (2012) and Hamed and Muhanna (2017) indicated the possibility of selecting homogenous new common bean lines with high yield.…”
