“…Brassica hirta Moench) is the most cold-tolerant species of the genus Brassica. It is also characterised by high drought tolerance, high resistance to weeds and relatively high resistance to pests (Brown et al, 2005;Kaasik et al, 2014). In comparison with Indian mustard (Brassica juncea L.…”

The aim of this study was to compare the thermal, physical, mechanical and chemical properties of white mustard (Sinapis alba L.) seeds of the traditional cultivar 'Radena' and the double low cultivar 'Warta'. The selected thermal properties were determined with an analyser KD2 Pro. Cultivar 'Warta' was characterised by higher thermal conductivity (0. ). Cultivars 'Warta' and 'Radena' had identical thermal diffusivity (0.087 mm 2 s -1 ). The values of the highest initial endothermic peaks and the last endothermic peak were determined from differential scanning calorimetry curves. The mean values of common peaks for both cultivars were determined at −17.5, 86.0 and 402.3 °C for 'Warta', and −16.5, 69.9 and 400

It is also tolerant to high temperatures and drought stress (Brown et al 1997), therefore S. alba has considerable promise as an alternative cruciferous oilseed crop in areas with short, dry growing seasons such as those found in the semi-arid regions of Western Canada and Australia (Rakow et al 2000).…”

Behaviour of Sinapis alba chromosomes in a Brassica napus background revealed by genomic in-situ hybridization

et al. 2005

Genomic in-situ hybridization (GISH) was applied to study the behaviour of addition chromosomes in first and second backcross (BC) progenies of hybrids between Brassica napus ssp. napus L. (AACC, 2n = 38) and Sinapis alba L. (SS, 2n = 24) produced by electrofusion. With GISH using genomic DNA of S. alba was used as probe it was possible to clearly distinguish both of the parental genomes and effectively monitor the fate of S. alba chromosomes in the BC(1) and BC(2) progenies. GISH analysis confirmed the sesquidiploid genome composition (AACCS) of the BC(1) progenies, which contained 38 chromosomes from B. napus and 12 chromosomes from S. alba. Genome painting in the pollen mother cells (PMCs) of the BC(1) plants revealed intergenomic association between B. napus and S. alba chromosomes, whereby a maximum of 4 trivalents between AC and S chromosomes were identified at metaphase I. In the BC(2) progenies, aneuploids with different numbers of additional chromosomes from S. alba, ranging from 1 to 7, were confirmed. Three putative monosomic alien addition lines were characterized, and the results are discussed with respect to the potential for intergenomic chromosome recombination.

“…In their experiments with plants from the family Brassicaceae Brown et al (2004) reported differences in Phyllotreta cruciferae injury both among species and among genotypes within one species; they found species differences in Phyllotreta cruciferare infestation and feeding injury regardless of the ontogenetic stage of seedlings.…”

In model experiments with leaf disks from Brassica napus L. subsp. napus and thlaspi arvense L. and Sinapis arvensis L. in spring periods (May-June) of 2006-2007 feeding preferences of Phyllotreta herbivores to the above-mentioned crop and two common weeds were investigated. In seedlings of identical ontogenetic stages insignificantly higher feeding injuries were recorded in B. napus. Between the two monitored weeds insignificantly higher herbivory was found in S. arvensis compared to t. arvense. In a comparison of older crop and younger weeds and vice versa, flea beetles significantly preferred the four-leaf seedling stage to the cotyledon seedling stage irrespective of the monitored plant species. Though generally in feeding preference of flea beetles a general drift B. napus > S. arvensis > t. arvensis was recorded, the sequence of leaves also played its role under conditions of this experiment.Keywords: feeding preference; crop; weeds; Brassicaceae; herbivory; Phyllotreta spp.; model experiments Recently, the role of injurious pests in agroecosystems has been re-evaluated, both of entomofauna and weeds, aimed to maintain the high level of biodiversity in agroecosystems.It is known that a subcritical amount of weeds increases the level of biodiversity and favourably influences the occurrence of pest antagonists.In this context the importance of weeds for pests themselves is evaluated less frequently, or the importance of another crop by way of "trap of pests" (Trdan et al. 2005) or biostrips (Lethmayer et al. 1997) in order to eliminate or compensate negative impacts of pests on the crop.Just from this point of view this paper is based on the question if some weeds could be preferred by herbivores. Considering the opinion that oilseed crops and cruciferous vegetables are of high economic importance and that cruciferous plants are ideal for biological studies as their chemistry is well understood and they support pest species from a wide range of insects (Finch & Collier 2000) the species of the genus Phyllotreta and family Brassicaceae were used in this study for model experiments.Feeding preferences of Phyllotreta spp. between (Brassica napus L. subsp. napus) -crop and (thlaspi arvense L.) and (Sinapis arvensis L.) -common weeds were investigated. MATERIAL AND METHODSModel experiments were conducted in the Crop Research Institute at Prague-Ruzyně in spring periods of 2006-2007.
