| Abstract | ||
| Two field experiments have been carried out one. The first in the station for research and agricultural experiments belongs to the college of agriculture university of al-Muthana ,during the spring season 2011. to formulate a singular hybrid from twenty pure offspring. the second one in al-Gharaf district Thi-Qar, during the autumn season 2011 to compare eleven singular hybrid( five of them formulated from the first experiment and six have been delivered from the general association for agricultural experiments. Abu-Ghraib) with their eleven fathers. Carried out according to Complete Block Design by three times. The male and female blossom period, the plant length, leaf size and cereal product and its components. After analyzing and evaluating the data the hybrid vigor and compare it to minimum and maximum results from the fathers according to the qualities, it has been found that all singular hybrids differed in its hybrid are vigor, in all studied characters, except in the quality of plant ear. When most hybrids have been positive hybrid vigor, save in AXB hybrid and CXB hybrid when the hybrids vigor have reached to 7.69% and 0.7% respectively. The results have shown that BXA hybrid has given the best value for the female blossom period (-10.63)% and female blossom (-9.22)% and the plant length (45.61)% and the line number in ear ( 34.74)% while the hybrid H-SF has given the best hybrid vigor, as the singular grain reached (53.16)% and the hybrid CXA for the grains number in line (51.230% and the grains product in plants is (91.77)% and the hybrid AX C for the leaf size (63.53)%. Thus, these results refer to the possibility of formulating a singular hybrid and planting it comparing with its fathers in study field, as well as replanting the hybrid in other sites and seasons to reach the inherited stability for the hybrid and present it for application and register | ||
