All but Topolea 57-77, released in 1977, were released in 1976. Careful evaluation from 1979 to 1981 compared varietal performance with that of high-yielding local varieties Timis and Diamant. The new Topolea lines yielded higher. Topolea lines have semidwarf stature, with height ranging from 50 to 59 cm. (av. 55 cm). Timis grows to 63 cm. The lines have short, dense, heavy panicles averaging 127 spikelets/panicle, each panicle weighing 1.9 g. Duration ranges from 105 to 123 d and is shorter in tropical zone. Average yield is 8.5 t/ha, versus 6.4 and 7.7 t/ha for Timis and Diamant. Topolea lines are lodging resistant, strongly resistant to cryptogamic diseases, and are N fertilizer responsive
