This experiment was conducted at the Agricultural Research Farm, NWFP Agricultural University, Peshawar to study the effect of multiple traits selection in a population of maize derived from maize variety Dehqan. The experiment was completed in two growing seasons during the years 2001 and 2002, raising one crop per year. In Kharif 2001, variety Dehqan was sown and selection for superior attributes was made on phenotypic basis. The selected (C,) and original population (C) were sown in the next Spring 2002 crop season along with two checks, a maize hybrid, Cargill 919 and an open pollinated maize variety, Sarhad Yellow. The genotypes were evaluated in a randomized complete block design (RCBD) using four replications, with 6 rows plot`, each 5 m long and 0.75 m apart. Highest number of days to 50% silking were recorded for Cargil 919 (68). Maximum days to 50% tasseling were recorded for Sarhad yellow (61), which were 3.39% more than Dehqan selected population (59). Maximum days to physiological maturity were recorded for Sarhad yellow (116), which were 3.57% more than Dehqan selected population (112). Maximum lodging percentage was observed for Dehqan original population (1.48%) as compared to Dehqan selected population (1.13%). Tallest plants were those of Sarhad yellow (176.75 cm), which were 11.87% taller than those of Dehqan selected population (158 cm). Dehqan original gave maximum ear height (59.5 cm), which was 7.27% more than that of Dehqan selected population (55.5 cm). This study indicated that one cycle of selection considerably helped in accumulating favorable alleles in the selected version of maize variety Dehqan.
