| Abstract | ||
| Field Experiments were carried at Abu-Ghraib Agricultural Station during the seasons of 2007 to 2009 for development and evaluation of maize (Zea mays L.) synthetics produced from different number of inbreds. Sixteen inbreds of maize were grow in 2007 to develop six synthetics according to polycross method. These synthetics were named Syn6 , Syn8 , Syn10 , Syn12 , Syn14 and Syn16. These involved according to there number of parents. These synthetics were planted during the spring seasons of 2008 and 2009 with check synthetic cultivars R-106 and 5012 . A randomized complete block design was used with four replications. Data on yield and its components were obtained. Results showed significant differences among the synthetics studied. Check cultivar 5012 gave higher means of grain number in ear and grain yield plant and total yield (114.26 g yield/plant and 7.616 ton/ha ) , respectively. Results showed that Syn16 was superior in yield and components as compared with other developed synthetics in spring seasons. The results also revealed that the grain yield and components of synthetics were increased with increasing number of inbreds parents , which will increase the genetic base. | ||
