Ornamental peppers have been attracting great commercial interest in recent years. However, despite the demand, the availability of ornamental pepper cultivars to growers and consumers is still reduced, which should stimulate breeding programs for improved varieties. In this context, the identification and characterization of accessions in ornamental pepper ... more

Breeding; Cultivated oat; SSR; Wild oat

Preservation and use of wild oat species germplasm are essential for further improvement of cultivated oats. We analyzed the transferability and utility of cultivated (white) oat Avena sativa (AACCDD genome) microsatellite markers for genetic studies of black oat A. strigosa (AsAs genome) genotypes. The DNA of each black oat genotype was extracted from young leaves and ... more

Breeding; Corn silage; Male sterility; Meiotic mutation; ms17

Cytological analysis under light microscopy of the single hybrid P30R50 of silage corn revealed an abnormal pattern of microsporogenesis that affected the meiotic products. Meiosis progressed normally until diakinesis, but before migration to the metaphase plate, bivalents underwent total desynapsis and 20 univalent chromosomes were scattered in the cytoplasm. At this stage, meiocytes ... more

Brachiaria; Breeding; Forage grass; Hybridization; Meiosis

Brachiaria humidicola is a grass adapted to seasonally swampy grasslands in Africa; two cultivars, ‘common’ and Llanero, are widely used in Brazilian pastures. New cultivars are in great demand in order to diversify current production systems to achieve improved quality and yield. Cytological analyses of 55 accessions of this species available from the Embrapa Beef Cattle ... more

Breeding; Hybrids; Meiosis; Silage corn

In breeding programs, commercial hybrids are frequently used as a source of inbred lines to obtain new hybrids. Considering that maize production is dependent on viable gametes, the selection of populations to obtain inbred lines with high meiotic stability could contribute to the formation of new silage corn hybrids adapted to specific region. We evaluated the meiotic stability of five ... more

Breeding; Carica papaya L.; Genetic resources; Genetic variability; Gower algorithm

We examined the genetic diversity of papaya (Carica papaya) based on morpho-agronomic and molecular data. Twenty-seven genotypes grown in Brazil were analyzed with 11 AFLP primer combinations, 23 ISSR markers, 22 qualitative, and 30 quantitative descriptors. For the joint analyses, we used the Gower algorithm (Joint Gower) and the average value of the individual dissimilarity ... more

Breeding; Genetic diversity; Phaseolus vulgaris; SSR markers

The identification of germplasm genetic variability in breeding programs of the common bean (Phaseolus vulgaris) is essential for determining the potential of each combination of parent plants to obtain superior genotypes. The present study aimed to estimate the extent of genetic diversity in 172 lines and cultivars of the common bean by integrating five tests of value for ... more

BmNPV; Breeding; Germplasm bank; RAPD molecular genetic markers

Brazil has only one public genetic pool of Bombyx mori strains, which was established in 2005 at Universidade Estadual de Maringá, Maringá, Paraná State. This genetic bank has been maintained, and the strains have been characterized using genetic and morphological tools. The quantitative and qualitative traits, directly or indirectly related to productivity, were evaluated in 14 ... more

Breeding; Fibroblast; Growth; QTL; SNP

In the past, the focus of broiler breeding programs on yield and carcass traits improvement led to problems related to meat quality. Awareness of public concern for quality resulted in inclusion of meat quality traits in the evaluation process. Nevertheless, few genes associated with meat quality attributes are known. Previous studies mapped quantitative trait loci for weight at 35 and 42 ... more

Brachiaria brizantha; Breeding; Forage grass; Microsporogenesis

The genus Brachiaria comprises more than 100 species and is the single most important genus of forage grass in the tropics. Brachiaria brizantha, widely used in Brazilian pastures for beef and dairy production, is native to tropical Africa. As a subsidy to the breeding program underway in Brazil, cytological studies were employed to determine the chromosome number and to ... more
