Vertical placement of roots within the soil determines their efficiency of acquisition of heterogeneous belowground resources. This study quantifies the architectural traits of seedling basal roots of bean (Phaseolus vulgaris), and shows that the distribution of root tips at different depths results from a combined effect of both basal root growth angle (BRGA) and root length. Based on emergenc...

ABSTRACT Sclerotinia sclerotiorum is a necrotrophic pathogen that devastates the yields of numerous crop species, including beans. The disease in common bean and pea is referred to as white mold. We examined the relationship between oxalate, an established virulence factor of S. sclerotiorum, and partial white mold resistance of scarlet runner bean (Phaseolus coccineus). P. coccineus genotypes ...

Fusarium root rot caused by Fusarium solani f. sp. phaseoli (Fsp) is widely distributed in Latin America. Experiments involving artificial inoculations could be better compared whether the number of Fsp infective propagules is well quantified by using chlamydospores. This study aimed to define the adequate concentration of chlamydospores of Fsp for assessment of the disease severity under contr...

Plant cells are able to shift their metabolism in response to aggressive environmental factors such as salinity, water stress, anoxia, flooding or biotic elicitors. In this work, cell suspensions of four bean (Phaseolus vulgaris L.) genotypes were stabilized and treated with elicitors isolated from fungal (Fusarium oxysporum f. sp. phaseoli) cell walls. The elicitation of the cells was effectiv...

common bacterial blight (cbb) of bean caused by xanthomonas axonopodis pv. phaseoli is a seriously important disease that adversely affects the quantity and quality of seed. cultivation of resistant cultivars is the most effective method of  the disease control. to identify disease resistant genotypes of selected beans, an experiment was conducted in  agriculture and natural resources research ...

ABSTRACT Iron and zinc deficiency is one of the main problems affecting vulnerable populations in Colombian Caribbean, thereby generating malnutrition from consumption foods with low content essential minerals. The objective this study was to evaluate genotype-environment interaction for iron accumulation grains 10 cowpea bean genotypes by additive effects multiplicative (AMMI) model select mos...

The number of experiments that allows the choice parents to be used in controlled crossings a more assertive way cluster analysis is unknown for plant architecture and grain yield traits common bean. Therefore, objective this work was determine should considered Tocher's unweighted pair group method with arithmetic mean (UPGMA) analyses identify promising bean several traits. Four were carried ...

Grain yield is a complex phenomenon, which results from the interaction of various contributing causes highly influenced by environmental variation. Phenotypic selection cannot directly improve characters in heterozygous crops like moth bean unless dissected genetic analysis. A study undertaken to determine extent variability for seed and ten other quantitative 40 genotypes bean. The analysis v...

One of the important edible legumes, faba bean (Vicia L.) contains high protein levels and amino acids in its seeds essential for human nutrition animal feeding; it also consists anti-nutritional factors such as vicine, convicine, tannin. For a balanced healthy diet, cultivars should be improved seed yield, acids, low factors. The aims this study were to select genotypes (i) (ii) factors, (iii)...
