Induction of Triticale (× Wittmack) In Vitro Androgenesis in Anther Cultures of F Hybrid Combinations, Varieties and Homogeneity Testing of Offspring Generation.

In cereal breeding, in vitro androgenesis methods are frequently applied to achieve doubled haploid (DH) plants. The aim of this study was to determine the effects of genotype (three registered varieties and eight F crossing combinations) and induction medium (W14mf and P4mf) on anther cultures (ACs) of triticale (× Wittmack). Androgenesis was induced in the treatment of each tested genotype, and the genotype significantly influenced the efficiency of AC, including in embryo-like structures (ELSs), albinos, green plantlets, and transplanted plantlets.

Utilization of in Vitro Anther Culture in Spelt Wheat Breeding.

The efficiency of in vitro anther culture was screened in a full diallel population of four spelt wheat genotypes and ten F hybrids. Genotype dependency was observed based on the data of embryo-like structures (ELS), green-, albino plantlets. In the diallel population and ten F hybrids, the green plantlets production ranged from 13.

Metabolic indicators of drought stress tolerance in wheat: glutamine synthetase isoenzymes and Rubisco.

Drought stress has a considerable impact on the ecosystem and agriculture. Continuous water deficit induces early leaf senescence in plants. During this process, chloroplasts are degraded and photosynthesis drastically drops.
