WebSeed development at 20±1° C in continuous light was studied during the first 5 days after pollination in diploid Hordeum vulgare, diploid H. bulbosum and the cross, H. vulgare x H. bulbosum, where H. bulbosum chromosomes were eliminated. Developing seeds were fixed and stained at known intervals after pollination and the embryo sac contents dissected … Webextracted and grown in vitro. The bulbosum method was the first haploid induction method to produce large numbers of haploids across most genotypes and quickly entered into breeding programs. Pollination with maize po llen could also be used for the production of haploid barley plants, but at lower frequencies.
