Cytology and reproductive behavior of hybrids between Paspalum urviUei and two hexaploid P . dilatatum biotypes

Sexual, tetraploid (2n = 4x = 40) vaseygrass (Paspalum urvillei Steud.) was crossed with two apomictic, hexaploid (2n = 6x = 60) dallisgrass (P. dilatatum Poir.) biotypes (Uruguayan and Uruguaiana) to determine their relationships and the reproductive behavior of the hybrids. One vaseygrass x Uruguayan and two vaseygrass x Uruguaiana hybrids were studied… CONTINUE READING
