Paspalum notatum cv. Boyero-UNNE is an apomictic-hybrid cultivar developed at FCAUNNE, Argentina. Here we evaluated seed development and phenotypic/reproductive stability through successive generations of Boyero-UNNE in the argentine temperate region (pampas). Plots were established at the FCA-UNR, Zavalla, Argentina. The development of seeds was examined by collecting 20 inflorescences every 3 days during the flowering period (21 days in total) and observing 50 spikelets/plant with a binocular microscope.
