Eight alfalfa clones, Medicago sativa L., were evaluated for self‐fertility and pollen growth characteristics under four temperature regimes (16, 21, 27, and 32 C). Highly significant differences were found among clones and among temperatures. Highly significant clone ✕ temperature interactions were found for self‐fertility, in vitro pollen germination, and in vitro pollen tube elongation. Pollen germination and tube elongation were not correlated with self‐fertility with one exception, self‐fertility and pollen germination at 16 C.
