بررسی ارقام گندم در بلوک های دورگ گیری و ایجاد نسل اول در ایستگاه زرقان در سال زراعی ‮‭1384-85‬

The basic role of improved wheat varieties in yield potential, and importance of the Fars province as the biggest wheat producer of Iran, necessitates the investment on genetic improvement of wheat, which begins with hybridization. One of the most principal ways by which new varieties of self pollinated crop originate, is hybridization. In this method two Jines or varieties are crossed, and plants in which the desirable features of the parents are combined, will be selected from the segregating progenies. With hybridization, the best characteristics of the parent single true breeding strain. In this evaluation more than 200 lines and varieties of native and international nurseries, were planted. Jt includes lines with high yielding, disease resistance, general or specific' adaptability, desirable grain quality and the commercial local varieties. One hundred eleven crosses were made, out of which 50 crosses had enough seeds. One hundred fifteen F 1 generations, originated from the last year hybridization program. partkipated in this evaluation and used for complementary crosses.
