Abstract EN
The performance of some barley genotypes was evaluated under rainfed conditions in Dara'a (Izra'a research station) Syria in two successive growing seasons, in order to assess the genetic variability of the source (stem and leaves) contribution to grain filling under rainfed conditions.
The trial was laid out according to the factorial complete randomized block design, with three replicates.
Significant genetic variation was found in the response of barley genotypes to water-limited conditions.
It was noticed that the stem contribution to the grain filling was significantly higher in the land races Acsad1602 and Acsad1614 (35.1, 29.2 g.
plant-1 respectively), while it was significantly lower in the all wild relatives.
The leaves contribution to the grain filling was significantly higher in the variety Acsad176, landrace Acsad1182 and the variety Acsad60 and the wild relatives Swaida'a and Amman.
Results showed that the ratio of leaves contribution to the grain filling was significantly higher during the first growing season (51.7%) compared to the second growing season (38.9%), that is due to the water stress which accelerating the translocation of assimilates from leaves to grain.
The 1000-kernel weight, grain yield were significantly higher in the varieties and land races compared to the wild relatives.
The grain yield was significantly higher in the second season (1113 g.m-2) compared to the first growing season (811 g.m-2).
