Multivariate approach to evaluating the fatty acid composition of seed oil in a doubled haploid population of winter oilseed rape (Brassica napus L.).
J Appl Genet. 2004; 45(4):419-25.JA

Abstract

The fatty acid composition of oil of the zero erucic acid commercial Brassica napus L. is typical for this species. It is rich in oleic acid and contains moderate levels of linoleic and linolenic acid. For human nutrition, it is advantageous primarily to obtain the highest possible content of oleic acid and to maintain the 2:1 ratio of linoleic to linolenic acid, while preserving the average total content of saturated acids. Uni- and multivariate analyses of variance were used for evaluation of doubled haploid lines of winter oilseed rape in respect of five fatty acids: palmitic (C16:0), stearic (C18:0) oleic (C18:1), linoleic (C18:2) and linolenic (C18:3). Some proposals of studying doubled haploid (DH) lines with the use of canonical transformation were also given. In MANOVA, the five original variables (individual fatty acids) were replaced by three 'new' variables (combinations of these acids) and used to evaluate DH lines with respect to the requirements concerning the nutritional role of fatty acids. The first variable was the total content of the saturated acids (C16:0 + C18:0), the second (unchanging) was the content of the monounsaturated acid C18:1, and the third was the difference between polyunsaturated acids, i.e. between linoleic acid, and the doubled content of linolenic acid (C18:2 - 2 x C18:3).
