“…Detailed reviews of glucosinolate content occurring in the major Brassica crops have been reported by several authors (Fenwick et al 1983b;Rosa et al 1997;Rosa 1999). Concerning B. napus crops, the glucosinolate composition in oilseed rape and swedes has been reported (Carlson et al 1981;Griffiths et al 1991;Rosa et al 1997). …”

Glucosinolate levels in leaves were determined in a collection of 36 varieties of nabicol (Brassica napus pabularia group) from northwestern Spain grown at two locations. Crude protein, acid detergent fibre, and sensory traits were also assessed by a consumer panel. The objectives were to determine the diversity among varieties in total glucosinolate content and glucosinolate profile and to evaluate their sensory attributes in relation to glucosinolate content for breeding purposes. Eight glucosinolates were identified, being the aliphatic glucosinolates, glucobrassicanapin, progoitrin, and gluconapin the most abundant. Glucosinolate composition varied between locations although the glucosinolate pattern was not significantly influenced. Differences in total glucosinolate content, glucosinolate profile, protein, acid detergent fibre, and flavour were found among varieties. The total glucosinolate content ranged from 1.4 mmol g À1 to 41.0 mmol g À1 dw at one location and from 1.2 mmol g À1 to 7.6 mmol g À1 dw at the other location. Sensory analysis comparing bitterness and flavour with variation in glucosinolate, gluconapin, progoitrin, and glucobrassicanapin concentrations suggested that other phytochemicals are probably involved on the characteristic flavour. The variety MBG-BRS0035 had high total glucosinolate, glucobrassicanapin, and gluconapin contents at both locations and could be included in breeding programs to improve the nutritional value of this vegetable crop.

“…The goitre fraction, progoitrin, and gluconapoleiferin (2-hydroxypent-4-enylglucosinolate), and the total glucosinolate content varied from 2.4 to 10.6 and 9 to 18.5 mol/g DM, respectively. Griffiths et al (1991) also found large differences between six cultivars and breeding lines in both the goitre fraction and total glucosinolate content. Results indicated the potential to select for high sugar and lower goitre and total glucosinolate content.…”

“…It causes hemolytic anemia in ruminants (Smith et al, 1974) but may be beneficial to non-ruminants, including humans, as it has been shown to lower cholesterol levels in plasma and liver (Itokawa et al, 1973). Griffiths et al (1991) found that bulb content in swede rose from 5.9 g/kg DM in July to a maximum of 9.9 g/kg DM in January, with a range from 7.2 to 9.3 in six cultivars and breeding lines averaged over nine harvests.…”

“…Of particular interest is gluconasturtiin (2-phenylethylglucosinolate), which is found in roots of brassicas but not usually in leaves (Bradshaw et al, 1984;Griffiths et al, 1991). Selections of rape for use as biofumigants have been produced with high levels of gluconasturtiin (Gowers, unpublished) and these could easily be transferred to swedes.…”

“…Nevertheless, swedes and turnips and generally considered to be safe crops and the bulbs are usually quite low in SMCO, although under some growing conditions they may contain enough SMCO to cause problems for ruminants (Griffiths et al, 1991). However, swede tops can be relatively high in SMCO especially in mid-winter (Griffiths et al, 1991).…”

Glucosinolates with Brassica genus as secondary metabolites have a lot of functions and effects. Glucosinolates form less than 2% of the overall sulphur content at the beginning of vegetation in different parts of the plants and during growth their content is decreasing and forms less than 0.1%. This low representation doubts their storage function. With its chemical composition, they are ranked among natural pesticides with active and passive resistance against diseases and pests. They show repellent effects and properties of natural biofumigators in soil after ploughing in their biomass as green fertilizing, or after ploughing in after harvest the leftovers of rape. The principle of these effects is decomposition products of glucosinolates-bioactive isothiocyanates. Very important from this point of view are turnip rape Rex and Brassica juncea, whose content of these compounds is the highest one and they are resistant against the attack of Ceutor-rhynchus pleurostigma. The same effect showed also when attacked by Phoma lingam. With other winter Brassicas either hybrid or linea and summer rape is this defensive system suppressed because of their lowered content due to breeding interferences, leading to limitation of their anti-nutritional negative effects. It is possible to state the final result after finding out the production of the above matter, roots, and after evaluation of the sorbal characteristics of the soil and evaluation of the state of health of the following crop or vegetable. After this overall analysis, it will be possible to evaluate the biofumigation properties of accessible varieties of the Brassica genus.
