“…The family x season interaction was significant in both cycles, indicating inconsistency in family performance in the test environments. This significant family x season interaction in common bean was frequently observed elsewhere (Arantes et al 2010, Menezes Júnior et al 2013). …”

“…Genetic gain in common bean breeding for disease resistance was also reported in some studies (Parrella et al 2008, Arantes et al 2010. Parrela et al (2008) were successful in breeding families that combine anthracnose resistance, high yield, erect plants and good bean appearance.…”

“…It is worth remembering that the higher the severity grade, the more susceptible is the genotype. Arantes et al (2010) evaluated the genetic gain for resistance to angular leaf spot in common bean and found indirect gain for grain yield and grain type after eight selection cycles (2.3% for yield and 2.5% for grain appearance).…”

“…The efficiency of recurrent selection in breeding autogamous plants, especially for common bean, was demonstrated for several traits (Sing et al 1999, Garcia et al 2003, Menezes Júnior et al 2008, Arantes et al 2010. Silva et al (2010) confirmed the efficiency of this strategy in breeding of common bean with carioca grain.…”

“…Thus, the procedures commonly used to compare selection cycles are assessments of families or lines of the different cycles, which can be done using standard controls (Arantes et al 2010) or the simultaneous assessment of the best families or lines of each cycle (Ramalho et al 2005, Menezes Júnior et al 2013). …”

A common bean (Phaseolus vulgaris L.) breeding program for resistance to Pseudocercospora griseola (Sacc.) Crous & U. Braun (angular leaf spot) using recurrent selection has been conducted since 1998 in Brazil. The selection has been carried out in the field with high natural occurrence of the pathogen. One recurrent selection cycle has been conducted per year. The efficiency of artificial inoculation of P. griseola and early assessment of angular leaf spot severity in common bean progenies of this program were evaluated. For this, 254 and 166 S 0:1 progenies from Cycles XVI and XVIII, respectively, were assessed for angular leaf spot severity in field, with natural occurrence of the pathogen and in greenhouse with artificial inoculation of P. griseola. Most progenies showed a high level of resistance to angular leaf spot, indicating the efficiency of recurrent selection. Artificial inoculation of P. griseola in the greenhouse showed promise for the selection of resistant plants in a recurrent selection program allowing breeders to carry out two cycles per year. A scheme was proposed that combined the advantages of early-generation selection with artificial inoculation of the pathogen in greenhouse with the advantages of selection in field with natural occurrence of P. griseola in the dry season, increasing genetic gain per unit time.

Cyclical phenotypic selection methods such as mass selection in open-pollinated (OP) cultivars were used widely in plant breeding until the inbred-hybrid approach began in the first half of the twentieth century. Mass selection was very effective to breed distinct OP cultivars but not for selecting high-yielding cultivars. This failure was due to selecting individual plants for a low heritability trait such as edible yield, low correlation of traits used in selection with edible yield, inappropriate male gamete control resulting from weak plot isolation, and poor plot techniques unable to control local environmental effects. Hence, population improvement methods, such as recurrent selection aiming to increase the frequency of favorable alleles by selecting the superior individuals in a population, intermating them, and selecting the best among their offspring, were sought in plant breeding (Hallauer et al. 2010). Recurrent selection differs from mass selection because selected individuals from the base population undergo progeny testing, and thereafter those selected based on this progeny testing data are intermated with each other to form the new population. Selection ensuing from recurrent selection can be further used in pedigree breeding for recycling inbred lines.
