Intraspecific breeding programs have been developed to exploit the sex inheritance mechanism in the tilapia Oreochromis niloticus to produce male populations. These programs are built on the premise that the mechanism of sex inheritance must conform closely to a monofactorial sex determination with a heterogametic male. Sex inheritance in tilapia, however, appears to be more complicated. The se...

One of the main reasons for oilseed rape breeding is to improve quality and composition seeds by increasing fat protein content, reduce dietary fibre. We attempted obtain such varieties crossing two DH lines winter different origin, H2-26 Z-114, which have black yellow seeds, respectively. The cross was followed in vitro androgenesis, resulting a population 44 that were studied field experiment...

Abstract Triticale is becoming an increasingly important livestock crop production. This evidenced by increasing triticale-producing areas and improved yields. In addition, meeting the demand for cereals involves introduction of high-yielding stress-resistant varieties into breeding. vitro culture techniques can accelerate development new varieties. Therefore, it seems extremely to develop effi...

Anther culture is the most effective and not technically complex tool for obtaining double wheat haploids. The current study devoted to research of influence genotype concentration growth regulator 2.4-D on efficiency androgenesis in vitro spring bread wheat. purpose was estimate anther hybrids first second generation their parental varieties its dependence different concentrations 2.4-D. There...

Aim. Protein content is known to be one of the most important characters grain quality. Investigation was aimed determine capability haploid production in anther culture vitro spring barley accessions which are sources high protein grain. Methods. Infrared spectroscopy used for evaluation variability genotypes content. Anthers isolated from cold-pretreated spikes were cultivated on agar solidif...
