DROUGHT RESISTANCE OF DURUM WHEAT VARIETIES AND LINES IN THE CONTROL FIELD

Abstract. 25 varieties and lines of rainfed durum wheat from the Control variety-testing field were evaluated for drought resistance under laboratory conditions. In a 15% sucrose solution, seed germination decreased by an average of 13%, while root length decreased by up to 35%. The lines KR21-DW-38, KR20-DW-17, and KR22-F6-DW-23 showed the highest drought resistance, while KR20-IDYT-15 and KR18-IDYT-25 showed the lowest resistance. The results indicate that these varieties and lines can be used in future breeding programs.
