INBREED DEVELOPMENT OF BEANS TYPE 'CARIOCA' ORIGINATING FROM TWO CYCLES OF RECURRENT SELECTION

摘要

In these last year, the beans plant genetic breeding programs have been giving emphasis to the breeding of cultivars from the commercial group "carioca", especially due to the preference of farmers and consumers for this type of grain. Thus, the development of new inbreed with elevated productive capacity and good grain quality has been the main goal for most of the breeding programs. Taking into consideration the fact that in order to obtain inbreed that associate grains within the commercial pattern of the "carioca" with high productivity, a great number of genes is involved. Therefore, an interesting breeding strategy is the use of recurrent selection cycles (Vieira et al., 2005). The aim of the present work was to evaluate the performance of beans inbreed of the type "carioca" extracted from twenty segregating populations, originating from the second recurrent selection cycle (Ci) of the beans plant breeding program at the Federal University of Vicosa - UFV, Vicosa, state of Minas Gerais, Brazil.
