ARTICLE – A half century of a bean breeding program in the South and Alto Paranaíba regions of Minas Gerais

Abstract: The success of bean (Phaseolus vulgaris L.) crops in Brazil is due to
the development of new cultivars. The aim of the present study was to critically
analyze the fifty years of a bean breeding program at the Universidade Federal
de Lavras (UFLA) and estimate the genetic progress (GP) achieved for grain
yield. The estimated genetic progress for grain yield was 0.35% per year, which
is associated with visible improvement in plant architecture, resistance to some
pathogens, and better carioca bean grain quality. The program was found to be
efficient, generating 119 theses and 43 dissertations during the period under
study. In addition, hundreds of articles have been published, especially studies
aimed at improving the efficiency of genetic breeding programs. Over the past
few years, partnerships with other public institutions in performing Value for
Cultivation and Use tests have resulted in 12 recommended cultivars.
