Abstract
Two field experiments were conducted at the Experimental Research Center, Faculty of Agriculture Moshtohor, Zagazig University (Benha Branch), Kaluibia Governorate during 1999 and 2000 growing seasons to evaluate ten new maize hybrids and study the association between yield and other related characters. in maize in both seasons.
The tested new hybrids included six single crosses namely, Moshtohor-8 (M 8) x M 199, M 8 x M 200, M 46 x M 210, M 234 x M 56, M 183 x M 199 and M 8 x M 201 and four three- way crosses (M 210 x S.C. 10, M 373 x S.C.
10, M 344 x S.C. 10) and M 360 x S.C. 10). The parental inbred lines of these hybrids were developed in the maize breeding program at the Faculty of Agriculture, Moshtohor, Zagazig University (Benha Branch). The three check varieties used in this investigation were: S.C. 10, T.W.C. 310 and Giza-2 which were developed by the Maize Research Section of the Agricultural Research Center, Giza Egypt. The experimental design was Complete Randomized Block Design with four replications in both seasons. Data recorded on date of silking, plant height (em), ear height (em), ear length (em), ear diameter (mm), number of rows/ ear, number of kernels/ row, 100- kernel weight, shelling percentage, grain yield (g/ plant) and grain yield (kg/ fad). "Data were analyzed separately for each season and combined analysis over both seasons according to (Steel and ToiTie, 1960).
The tested new hybrids included six single crosses namely, Moshtohor-8 (M 8) x M 199, M 8 x M 200, M 46 x M 210, M 234 x M 56, M 183 x M 199 and M 8 x M 201 and four three- way crosses (M 210 x S.C. 10, M 373 x S.C.
