Selective Control

Control of Canada thistle (Cirsium arvense L. Scop.) topgrowth and regrowth, and tolerance of rapeseed (Brassica campestris L. and Brassica napus L.) to 3,6-dichloropicolinic acid at 0.2–0.3 kg/ha were excellent in greenhouse and field trials. Rapeseed yields following postemergence treatment were increased in 12 of 17 trials conducted on infested farm fields.

Brassica Crops

Five genes have been identified in Brassica crops which control the level of synthesis of the fatty acid, erucic, in their seed oils. These genes, designated e, Ea, Eb, Ec, and Ed, act in an additive manner and result in erucic acid levels of < 1, 10, 15, 30 and 3.5, respectively. No direct evidence has yet been obtained to show that these genes are true alleles. Selected plants of the amphidiploid species Brassica napus L. with erucic acid contents of 7–8% and a genotype of EdEdee were reciprocally crossed with selected plants with erucic acid levels of [Formula: see text] and a genotype of Eaeee. Fatty acid analysis of F1 and backcross seed demonstrated that the genes Ed and Ea in the parents used were in the same genome and were truly allelic. Interspecific crosses were made between these B. napus parents and selected zero erucic acid plants of Brassica campestris L. (genotype "ee") to determine whether the genes Ed and Ea resided in the oleracea or the campestris genome of B. napus parents. Fatty acid analysis of F1 and backcross seed from these interspecific crosses suggest that the alleles of Ed and Ea are located on chromosomes of the oleracea genome.

Sulfur Containing

Two proteins, previously described by the authors as BI (S020, buffer 12 S) and AIVS (S020, w 1.7 S) have been isolated from eight varieties of rapeseed belonging to Brassica campestris L. and Brassica napus L. species. These proteins have similar chromatographic and electrophoretic characteristics but differ in amino acid composition, particularly with regard to the sulfur-containing amino acids. One of the rapeseed samples was obtained from plants grown on sulfur-deficient soil. The sulfur deficiency produced, in the mature seed, a much reduced protein content and appeared to affect the structure of the protein BI.
