    Notes: Summary Calli were initiated from immature embryos of eight lines of hexaploid wheat (Triticum aestivum L. em. Thell) with different cytoplasms, the euplasmic nuclear donor ‘Chinese Spring’ and seven alloplasmic lines derived from wild relative species of the genera Triticum and Aegilops. The calli were found to differ in their initial growth rates, their sensitivity to 2,4-D and their ability to organise shoot primordia, demonstrating that the cytoplasm can significantly affect the behaviour of tissues in culture. The potential for improving the responses of tissues in culture by cytoplasmic changes is noted.

    Topics: Biology
    Notes: Summary Calli were initiated from immature embryos of four lines of hexaploid wheat (Triticum aestivum L. em. Thell), the euplasmic nuclear donor ‘Chinese Spring’, ‘Chinese Spring’ in which both 4B chromosomes were substituted by those of the variety ‘Cappelle-Desprez’ and two alloplasmic lines in which these nuclei were substituted into the cytoplasm of Aegilops ovata. The calli were found to differ in their initia growth rates and their ability to organise shoot primordia and regenerate shoots. The ‘Cappelle’ 4B chromosomes had a very significant effect on all these characters. The potential for modelling genotypes for improved tissue culture characteristics is discussed.
