Abstract

The Instituto Agronomico de Campinas - IAC registered the carioca type common bean cultivar IAC Milenio. The cultivar has a mean yield of 2831 kg ha-1, high grain quality with tolerance to darkening, and resistance to Fusarium oxysporum and physiological races 81, 89, and 95 of the anthracnose pathogen (Colletotrichum lindemuthianum).

Highlights

The cultivar has a mean yield of 2831 kg ha-1, high grain quality with tolerance to darkening, and resistance to Fusarium oxysporum and physiological races 81, 89, and 95 of the anthracnose pathogen (Colletotrichum lindemuthianum)
Common bean (Phaseolus vulgaris L.) is one of the most important constituents of the Brazilian diet as it is an excellent source of protein
The main goal of the common bean genetic breeding program of Instituto Agronômico de Campinas (IAC) is to develop common bean cultivars that have high grain quality, especially for the characteristics of size and appearance, as well as to develop cultivars resistant to at least one of the main diseases that attack the crop, within the context of anthracnose as the main disease worked with in plant selection; genotypes susceptible to this pathogen are not released on the market

Summary

Introduction

Common bean (Phaseolus vulgaris L.) is one of the most important constituents of the Brazilian diet as it is an excellent source of protein. In addition to its importance in the Brazilian diet, it is an agricultural product of great economic and social importance as it is grown in large areas and due to the laborers employed during the crop cycle (Carneiro et al 2012, Pereira et al 2012) In consideration of this importance, the common bean genetic breeding program of IAC, carried out in the Centro de Análise e Pesquisa Tecnológica do Agronegócio dos Grãos e Fibras of the Instituto Agronômico de Campinas (IAC), Campinas, São Paulo, has made high-yielding common bean cultivars of the carioca grain type available to the productive sector (Carbonell et al 2008, Carbonell et al 2010, Chiorato et al 2010). Selections for anthracnose are made in early F2 and F3 generations, and the selection method applied is genealogical
