The success of any breeding program depends on the ability of the breeder to select genetically superior progenies for multiple traits simultaneously, and an alternative is the use of selection indexes. In this study, the selection indexes of Smith-Hazel, Base Index, Sum of Ranks, and Index Z were used to select superior upland rice progenies for four important agronomic traits. Five commercial cultivars and 191 progenies F2:4 of upland rice were evaluated for days for flowering, plant height, blast resistance, and grain yield in four environments. The genetic correlation between pairs of traits, the response of selection in each trait and the correlated response considering the selection for number of days to flowering and the response in grain yield were... |

Anthracnose, caused by the fungus Colletotrichum lindemuthianum (Sacc. and Magn.), is one of the most important diseases affecting the common bean (Phaseolus vulgaris L.) in Brazil. Based on the level of susceptibility shown by the cultivars, the occurrence of environmental conditions favorable to the development of the disease, and the amount of initial inoculum present, losses in the seed yield and quality can range from 80 to 100%. The main goal of the present work was to identify the inheritance of anthracnose resistance in the Andean cultivar BRSMG Realce. |
