Abstract:
The problem of the scarcity of water resources is one of the issues of paramount importance in this region, as work is being done to study and test the ability of crop varieties such as lentils to withstand drought conditions during the different stages of growth. The experiment was carried out at the one of May research station, GCSAR in Damascus Countryside during the growing season 2020-2021 with the aim of evaluating the tolerance of ten varieties of lentil to the water stress applied during the flowering stage in the field, With split plot design. The results of the experiment showed the variation of the studied lentil models in their performance under stress conditions, and it was noted that the G19 genotype achieved the lowest percentage of decline in the number of days until flowering by 1.15%, while the G8 genotype achieved the highest percentage of decline by 4.28%, and the G15 genotype achieved the lowest percentage of decline in the number of days. Until maturity, at a rate of 5.92%, and the G4 genotype achieved the highest percentage of decline by 16.04%, and in the case of plant height, the G20 genotype achieved the lowest percentage of decline by 2.62%, while the G16 genotype achieved the highest percentage of decline by 43.73% In the case of 100 seeds, the G19 genotype achieved the lowest percentage of decline by 2.25%, and in the case of the number of pods on the plant, the G3 genotypes achieved the lowest percentage of decline of 5.31%, and the genotypes G15 and 11G achieved the highest productivity under stress conditions, which reached 3.88, 2.45 tons / e with a decline rate of 25.37 and 28.58%, respectively, but the G20 genotype achieved the lowest yield decline compared to the control, which did not exceed 8.10%, and therefore it is considered the most tolerant, although its productivity was basically low under the conditions of the witness 1.07 tons / h. Therefore, we suggest introducing the 20G genotype in the breeding programs to improve drought tolerance, as well as in the breeding programs directed to increase yields in order to improve its productivity. We also suggest adopting the genotypes G11 and G15, in areas with low rainfall.
Keywords: lentils, drought stress, flowering, productivity, developmental and productive traits.
