ملخص المقال

The present research was conducted at the experimental field of the Algerian
National Agronomic Research Institute (INRAA), Unit of Setif during the 2012/2013
cropping season. It focused on screening and analyzing the variability within F2
populations generated by line x tester mating design. The results indicated the
presence of sufficient variability within and between F2 populations for the
measured variables: the phenology, tolerance of abiotic stresses including water
deficit and high temperatures and the grain yield. The principal component analysis
divided the different F2 populations into 10 groups which differed for more than
one character, suggesting that different selection strategies are available to
improve more than one character at the same time. Thus populations that had
favorable genes for grain yield and resilient against abiotic stress have been
identified. The results showed that no population was desirable for all the
characters measured.
