POSSIBILITIES OF DEVELOPMENT OF HIGH OLEIC LOW LINOLENIC SPRING RAPESEED AT V.S. PUSTOVOIT ALL-RUSSIAN RESEARCH INSTITUTE OF OIL CROPS

Statistical analysis of some economically valuable traits of spring rapeseed plants of variety Amulet was carried out, as a result of which strong variation of seed weight per plant (28.9 %), medium variability of linolenic acid content in seed oil (12.7 %) and weak variation of oil content and oleic acid content (4.2 and 2.0 %, respectively) were found. High correlations were found between oleic acid content and plant productivity (r = 0.76) and oil content of seeds (r = 0.99), and between oil content and productivity (r = 0.76). A moderate negative relationship was found between linolenic acid levels and yield (r = -0.37) and oil content (r = -0.43). The obtained data indicate a sufficient number of genotypes with the necessary combination of high yield, oil content, oleic acid content and low level of linolenic acid in spring rapeseed seed oil.
