In Toshkëz district of Lushnja, the group of genetic improvement of AgroARFA crops, maintain a scientific activity with the maize culture, in testing some of the best hybrid versions circulating in the country with high results in the production of maize. Their origin is mainly from Italy and new hybrid combinations of our company. The purpose is not only to determine the best foreigner hybrids, but also to be tested in parallel with the levels of our new hybrid combinations. For those who give high scores to suit our conditions, they are recommended to be used. In this statement we give results of hybrids and new hybrid combinations carried out in 2014-2015. From all the work out it is shown that hybrid combinations between lines synthesized in our country represent a significant variation of performances yield which is related to their genetic consistency.Nine lines are well combined with intersections (tester) lines:AS12; AS19 and AS20. Hybrid combinations with high expectations such as AS18xAS20, AS17xAS19 and AS12xAS18 enter the state testing network. From foreign hybrids with higher levels of performance we would distinguish hybrids: DKC 6815 and SNH 8605.
