Compound inflorescence; Genetic components; Heritability; Phaseolus vulgaris; Plant breeding

The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyzed the genetic control of this ... more

Disease resistance; Inheritance study; Phakopsora pachyrhizi; Plant breeding; Resistance gene

Soybean rust (SBR), caused by the fungus Phakopsora pachyrhizi, has been reported in common bean (Phaseolus vulgaris L.) cultivars and elite lines that were infected under controlled and natural field conditions in South Africa, the United States, Argentina, and Brazil. Although SBR is currently not a top priority problem for the common bean crop, many bean breeders are ... more

Experimental design; Genotype by environment interaction; Monte Carlo simulation; Plant breeding

In this study, we aimed to establish strategies for value for cultivation and use (VCU) experiments for the tobacco crop in the southern region of Brazil with respect to the number of environments used to assess tobacco lines. Trials of the Virginia (18 sites) and Burley (17 sites) varietal groups were conducted in the three states of the southern region of Brazil in the 2009-2010 crop ... more

Bayesian shrinkage analysis; common bean; Plant breeding; Quantitative trait loci; Sclerotinia sclerotiorum

In this study, we identified simple sequence repeat, ampli­fied fragment length polymorphism, and sequence-related amplified poly­morphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and using Bayesian analysis. DNA was extracted ... more

Allelochemicals; Genetic resistance; Plant breeding; Solanum lycopersicum; Solanum pennellii

Acyl sugars present in the tomato Solanum lycopersicum ‘LA-716’ accession confer good levels of resistance to arthropod pests. The objective of the present study was to select F2 plants from the interspecific cross Solanum pennellii ‘LA-716’ x Solanum lycopersicum ‘Redenção’ to assess resistance to spider mites (Tetranychus urticae) based on ... more

Early selection; Genetic effects; Grain yield; Hybrids; Seed quality tests; Zea mays L.

Studies of genetic effects of early selection of maize based on seed quality traits are rare, especially those that use materials from different heterotic groups. These studies are also useful in tropical environments and for the advancement of sustainable agriculture with cropping during seasons not commonly used for cultivation. We estimated, through diallel crosses, the predominant ... more

Cydonia oblonga; ISSR; Morpho-agronomical descriptors; MRA; Quince

Quince is a deciduous tree known to the countries around the Mediterranean since antiquity. Nowadays, quince is used as an ornamental plant, and as a rootstock for pear trees, with its fruit being appreciated mainly for production of jam and sweets rather than for raw consumption. Quince leaves contain compounds with antioxidant, antimicrobial and anticancerous properties that have been ... more

Isolates of entomopathogenic fungus Metarhizium anisopliae var. anisopliae were characterized using internal transcribed spacer-RFLP, ISSR and intron splice site primers. Thirty-seven isolates were studied, most of which were obtained from the sugar cane pest, Mahanarva fimbriolata (Hemiptera: Cercopidae) from Tangará da Serra, Southwest Mato Grosso State, ... more

Bamboo; Crossbreeding; Hybrid identification; ISSR; Suspected hybrid

Crossbreeding is an efficient means to increase production and quality in plants; however, hybridization is seldom reported in bamboo. We crossbred two bamboo species Phyllostachys kwangsiensis (female parent) and Phyllostachys bambusoides (male parent) for the first time, and obtained suspected bamboo hybrids. We identified two bamboo hybrids from the above parents ... more
