A breeding program was initiated at the Research Institute of Vegetable Crops, Skierniewice, Poland to select new tomato lines resistant to bacterial speck (Psedomonas syringae pv. tomato (PST) and suitable for field growing. Two tomato cultivars with good agronomic characteristics Luban and Rumba were crossed with resistant to PST ‘Ontario 7710’. Then backcross and pedigree breeding procedures...

The effects of the various evolutionary factors-mutation, cross breeding,. selection and inbreeding-can be reduced to common terms by considering the rates of change which they tend to bring about in the relative frequencies of alleles.' In the absence of such factors, there is constancy of gene frequencies from the symmetry of the Mendelian mechanism. The frequency (q) of a given gene changes ...

The Crop Ontology (CO) of the Generation Challenge Program (GCP) (http://cropontology.org/) is developed for the Integrated Breeding Platform (IBP) (http://www.integratedbreeding.net/) by several centers of The Consultative Group on International Agricultural Research (CGIAR): bioversity, CIMMYT, CIP, ICRISAT, IITA, and IRRI. Integrated breeding necessitates that breeders access genotypic and p...

The aim of the this study was to identify SNP markers associated with five important wheat quality traits (grain protein content, Zeleny sedimentation, test weight, thousand-kernel weight, and falling number), and to investigate the predictive abilities of GBLUP and Bayesian Power Lasso models for genomic prediction of these traits. In total, 635 winter wheat lines from two breeding cycles in t...

the best method of fish breeding is the isolation of pure lines having high-producing hybrids. the decline in heterosis (dih) resulted from inbreeding, maternal effects, general combining ability (gca) and specific combining ability (sca) on reproductive traits (e.g., egg production, number of hatched egg, and hatchability of pure lines and crosses) of tiger, green, and albino barbie hybrids we...
