Résumé
Breeding alfalfa varieties for high forage and seed yield production suitable for growing in the new valley. These field experiments were carried out during three successive seasons 1999/2000,2000/2001 and 2001/2002 at the Experimental Farm of new valley Agricultural Research station, El-Kharga Oasis. The study began by collecting seeds of 14 local alfalfa populations from farmer’s fields in the major areas for alfalfa production in the New Valley. Evaluation of the populations for high forage production in experiments (Experiment I), selecting field and hybridization for producing the groups as follows : 1- (b1) original population. 2- (b2) pollycross (open pollinated seeds resulting from first selfed (S1) plants). 3- (b3) ) pollycross (open pollinated seeds resulting from second selfed (S2) plants). 4- (b4) open pollinated seeds resulting from plants succeded in self pollination (self-sterile plants). 5- (b5) open pollinated seeds resulting plants from plants field in self pollination (self-sterile plants).
