Fusarium wilt is a serious soil disease affecting common bean cultivation, especially crops under a central pivot irrigation system. Our objective was to identify bean lines that combine resistance to Fusarium wilt in the field with other desirable traits. Twenty-eight randomized block trials with three replicates were conducted  in the rainy, winter, and dry ... more

A possible strategy to increase grain yield in common beans (Phaseolus vulgaris) is to obtain lines with earlier flowering and a longer grain filling period, associated with a higher dry matter accumulation rate. We examined the genetic control of these traits to investigate whether it is possible to select lines with earlier flowering, a longer period of ... more

Conservation; Genetic variability; Phaseolus vulgaris

Conservation of seeds ex situ is an important strategy for maintaining genetic resources. Mulatinho type common beans are widely cultivated and consumed in regions with extreme climatic conditions with semi-arid characteristics, including low fertility soils, and a dry and hot climate, such as in northern Minas Gerais state and the northeast region of ... more

Cooking time; Phaseolus vulgaris; Seed darkening; Technological quality

High temperature is one of the main environmental factors that limit crop performance. It may also influence seed formation and quality. We compared the effect of high temperatures on seed darkening and cooking time of 12 genotypes of common beans. The experiments were sown in summer and in fall/winter growing seasons in three municipalities of São Paulo state ( ... more

Correlation; GGE-biplot; P deficiency; Phaseolus vulgaris; root system

An inadequate supply of phosphorus (P) is one of the most limiting factors for plant nutrition, resulting in morphophysiological adjustments and reduced production. We evaluated 42 common bean germplasm bank accesses of the Instituto Agronômico Brazil that are divergent in root traits, using a hydroponic system to determine their performance under P deficiency. The ... more

Correlation; Grain yield; Phaseolus vulgaris; Water deficit

ABSTRACT.  Common bean yield is directly related to climate conditions, and water deficit is one of the main limiting factors. One way of getting around this problem is increasing the frequency of alleles favorable to drought tolerance by the recurrent selection method. We estimated the morphophysiological and agronomic gains achieved in two ... more

Knowledge of the genetic structure of a trait shapes the entire strategy of a breeding program. In this study, the purpose was to determine the additive and non-additive effects that affect the genetic control of common bean roots. A field experiment, with 75 treatments in a partially balanced incomplete block design, was carried out in the 2018/19 growing season. ... more

The development of common bean plants with an improved root system can be a strategy for water and nutrient absorption in limiting environmental conditions. The objective of this study was to understand the influence of root phenotyping methods and phenological stages of evaluation on the selection of common bean genotypes for a highly branched root system. In the ... more
