Anther culture-derived haploid embryos were used as explants for Agrobacterium-mediated genetic transformation of bread wheat (Triticum aestivum L. cv CPAN1676) using barley HVA1 gene for drought tolerance. Regenerated plantlets were checked for transgene integration in T₀ generation, and positive transgenic haploid plants were doubled by colchicine treatment. Stable transgenic doubled haploid ...

The development of cauliflower (Brassica oleracea var. botrytis) is highly dependent on temperature due to vernalization requirements, which often causes delay and unevenness in maturity during months with warm temperatures. Integrating quantitative genetic analyses with phenology modeling was suggested to accelerate breeding strategies toward wide-adaptation cauliflower. The present study aims...

Rice (Oryza sativa L.) is an important global food commodity crop. Its yield was affected by genotype, environment, and the interaction between genotype environment that demands development of diverse tolerant rice to increase yields adaptation. Genotype Environment for Tongil types with doubled haploid (DH) were evaluated in three locations. A randomized complete block design replicated times ...

By using a doubled-haploid population derived from F2 plants, additive and additive X additive genetic variances, as well as the number of segregating genes, can be estimated. An F2-derived doubled-haploid population may contain almost 50% more of the best recombinant than an F1-derived population. However, the best recombinant occurs in the same frequency in the two populations when there is n...
