Experimental work was carried out from November 1989 to March 1989 at Cumbacillo, in Morales district, province and depatment of San Martín and at a high sea level of 300 m. We evaluate yielding and additional characteristics of lines and hybrids of tropical maize, We use a partial simple lattice design with 56 tratments and two repititions. Resums were analysed with a Variance test and a LSD 50%. Experimental área was an alluvial soil, flat and mechanized, slightly acid (ph 6.5), low organic matter (1.5%) Nitrogen, phosphorous 3 ppm and potassium 137 ppm. Seeds were grown in wet soil, 0.80 m between plants and furrows. Culture had three irrigation and was fertlized with 90 kg. Urea (45% N) 60 kg. of Calcium Superphosphate (46% P2 05) and 30 kg potassium plus othre 50% Nitrogen were applied at the conmming out sedes, the other 50% Nitrogen ofter 30 days. Statistical analysis show significative high diference among treatment when ajusted the grain yielding to 14% humidity. Vields fluctuate from 4.86 Tn/ha to 1.4 Tn/ha, respectively to R.D.4 x Gua.6 and Gua.8 x R.D.4 Together with R.D.4 x Gua.6 excslded by their high yielding Mg.2 z Col.3, Cb.1 x Col.3, Mg.2 x Bra.2, R.D.7 x Mg.2, Mg.2 x Col.3, Cb.1 x Bra.2, Cb.1 x mg.2 y bol.2 x R.D.4 among them there were not any statistical difference and were ahove the varietal check Marginal 28 Tropical (M- 20-T) with 2.03 tn/ha and placed 52 range of positional table. The best nine hybrids are recommended for growing in another área with similar soil and climatic conditions. Besides, we find that R.D.4; R.D.7; Col.3; bra.2; Mg.3; Cb.1 and gua.8 lines were relativaly high tan M-28-T, without showing any statistical difference among them.
