RESULTS OF TESTING OF REGENERANT LINES OF SPRING SOFT WHEAT IN THE NORTH KAZAKHSTAN
The article presents results of testing of regenerated lines of spring soft wheat in the control and the preliminary variety testing in the fields of SPC by the name of A.I. Barayev, in the Northern Kazakhstan. During conditions of the growing season, duration of the vegetation period for ripening was 1–4 days longer for the tested lines compared to the standard variety Akmola 2. By resistance to drought all lines of spring wheat conformed to standard, except for the 4–th line. By lodging resistance, line 80/95 with 0,3 % NaCl № 5 exceeded Akmola 2 standard. By the yields in the preliminary variety testing, several lines exceeded Akmola 2 standard by 0,9–6,9 cent/ha, namely the lines 99/03 with 0,4 % NaCl № 2–1–1, 504/01 with a 0,4 % NaCl № 1–2–1, 467/97 with 4.3 % PEG № 5–1, Akmola niva with 70 % of F.g. № 3–1, 8/03 MS № 4–2 and 80/95 with 0,3 % NaCl № 5.
