AGRONOMIC CHARACTERIZATION OF TROPICAL MAIZE (Zea mays L.) INBRED LINES CONVERTED TO QUALITY PROTEIN CHARACTER
Maize inbred lines converted to the quality protein character were evaluated for grain yield and agronomic traits. The stu - dy was carried out in the Experimental Station Cotaxtla, Ve - racruz, Mexico, during the autumn/winter 2011/12 and spring- summer 2012 seasons. The experimental design was an...

The experimental design was an alpha latice 16×8 with 128 treatments and two replications, with one- row plots 2.5m long, 80cm wide and a density of 62500 plants/ ha. During crop development, data were recorded about plant and ear height, days to tassel and silking, plant and ear aspect and sanity, ears with bad husk cover, ear rots, grain yield, gra - in texture and segregation of the opaque character in the gra - in. Throughout genotypes (G) and environments (E), the ma - jority of traits except for ears with bad husk cover were signi - ficant. The analysis of variance combined in two evaluation environments, found statistical significance for G and E, for all traits, except for ears with bad husk cover. For interaction G×E significant differences for grain yield, days to pollen-shed and silking and lodging were found.
