Seed performance of three interespecific hybrids of elephant grass × pearl millet under controlled deterioration
The interespecific hybrid Pennisetum purpureum ( elephant grass) × P.glaucum ( pearl millet ) has been developed with the goal of getting the rusticity and high forage production of elephant grass and the high production of pure seeds of pearl millet (Schank et al., 1996).However, it revealed low phenotypic uniformity (around 50.0％ ) as well as low pure seed production (5 ‐10.0％ ).A recurrent selection scheme has been applied, resulting in two populations (Cutting‐and Grazing‐types), showing high phenotypic uniformity ( around 80.0％ ) and a good pure seed production ( around 30.0％ ) ( Usberti et al., 2005).The goal of this work was to analyze their seed performances with controlled deterioration.
