Glucosinolate content of rapeseed (Brassica napus L.) meal was investigated in parental, hybrid and segregating populations derived from the cultivar Bronowski, and a strain derived from Target. The gluconapin, glucobrassicanapin and progoitrin content of seed meal was determined by the genotype of the maternal plant, rather than the embryo genotype. Higher values of gluconapin were partially dominant to the lower values. Three loci were indicated in the control of gluconapin content. Overdominance of high values of glucobrassicanapin was demonstrated. Four or five loci probably control glucobrassicanapin content. The high values of progoitrin were partially dominant to the absence of progoitrin. Four loci were indicated for progoitrin. The gene systems controlling the three compounds did not segregate independently of each other.

Meal Quality

The effect of time of sowing on the oil and meal quality of rapeseed (Brassica napus L. cv. Marnoo) was investigated at Werribee, Victoria, during 198 1 and 1982. In both years oil content declined with later sowing but the proportion of erucic acid in the oil was unaffected by sowing time. In contrast, later sowing increased the glucosinolate content of the seed meal, with July-September sowings exceeding the Canola standard. This increase was due primarily to the increased content of 2-hydroxybut-3- enyl glucosinolate (progoitrin).

Ad Libitum

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.

The content of aliphatic, aromatic and indole glucosinolates were measured in the roots, hypocotyl, cotyledons and leaves of the high glucosinolate Brassica napus cultivar Midas over the first 10–14 d after seeding. For seedlings grown in light from emergence, glucosinolate content declined slightly then increased. Increase in the indole glucosinolate content of the shoot (hypocotyl and cotyledons) was caused by an increase in 3-indolylmethyl glucosinolate. When seedlings were confined to darkness for either 6 or 10 d after seeding, 3-indolylmethyl glucosinolate did not increase. The content of 4-hydroxy-3-indolylmethyl the dominant glucosinolate in the seed, declined in both light and dark grown seedlings. The individual glucosinolates in different parts of the seedling appeared to vary independently and to be related to development of specific organs or tissues. The complexity and relative rapidity with which amounts of the individual glucosinolates changed suggests the existence of an intricate metabolic control.Key words: Rapeseed, Brassica napus L., Cruciferae, glucosinolate, seedling development
