Nodulation; Phaseolus vulgaris; Rhizobium; SNF

Nitrogen (N) is the most important soil nutrient for common beans; the main sources are mineral N fertilizers and symbiotic N fixation (SNF). The common bean (Phaseolus vulgaris) is a N fixing species, but breeding programs have neglected this fact. We investigates black seeded elite lines grown with mineral N fertilization or using inoculation with ... more

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

Grain Production Physiology; Phaseolus vulgaris; Plant breeding; Quantitative genetics

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

Fusarium wilt (also known as Panama disease) is one of the most destructive banana diseases, and greatly hampers the global production of bananas. Consequently, it has been very detrimental to the Chinese banana industry. An infected plant is one of the major causes of the spread of Fusarium wilt to nearby regions. It is essential to develop an efficient and ... more
