    Factors to affect inbred beet plants while developing material for linear selection by M. I. Fedorova, E. G. Kozar, S. A. Vetrova, V. A. Zayachkovskyi, V. A. Stepanov

    Published 2019-07-01
    “…In inbred plants, there is no close relationship between pollen viability and seed productivity, because the elimination of germinated male gametes and degeneration of seed embryos may go over the entire period of fertilization starting its progamic phase. The SI plants have more degenerating embryos than self-fertile ones, but seed vessel outgrowth in the seeds with abortive embryos makes them morphologically similar to fertile seeds. …”
