Composition and correlation studies of fatty acids in seed oil of yellow sarson (Brassica campestris L.) cultivars and backcross derived zero erucic acid yellow sarson populations

Genetic analysis of F2, F3, and backcross populations supported the hypothesis that erucic acid content in seed oil of plants of Brassica napus L. is governed by two genes displaying no dominance and acting in an additive manner. Environment appeared to influence erucic acid content, especially in genotypes capable of producing a large amount of this acid. Methods for the breeding of plants of Brassica campestris L. with zero erucic acid are outlined and it is suggested that similar methods could be used to breed for or against other fatty acids.

Fractionation Method

The fatty oil of hare's-ear mustard seed (Conringia orientalis L.) was examined. Constants of the oil were determined and a partial separation of the fatty acids was carried out by the methyl ester fractionation method. Palmitic, oleic, linoleic, eicosenoic, erucic, and lignoceric acids were identified. Erucic acid was found to be present in largest amount. The oil resembles rapeseed and other Cruciferae seed oils in this respect. The content of eicosenoic acid is estimated to be not more than 12% of the total fatty acids.

Brown Sarson

Reciprocal crosses were made between a plant of Brassica campestris L. containing no erucic acid in its seed oil and two plants of the Indian varieties Yellow and Brown Sarson grown from seed containing approximately 59% erucic acid. The erucic acid content in the oil from F1 embryos was intermediate between the parents indicating embryonic control of the synthesis of this acid. Seed oil analysis of F2, F3, and backcross populations supported the hypothesis that erucic acid synthesis is controlled by a single non-dominant gene. Analysis of oil extracted from immature and partially germinated seed showed that erucic acid content was highest in fully matured non-germinated seed.
