    Development of an alternative system for seed-based tobacco haploid plant generation

    MOORE S.; KERNODLE S.P.; LEWIS R.S.
    Department of Crop and Soil Sciences, North Carolina State University, Raleigh, NC, U.S.A.
    Haploid plants can be extremely useful for expediting the production of new inbred lines, and also for rapidly converting female parental lines of new hybrids to cytoplasmic male sterility. Use of doubled haploid breeding can increase gain from...
