“…These results confirm the conclusions drawn by WILLIAMS and SOBERING (1992), , VELASCO et al (1999a) that NIRS analysis may facilitate effective selection of oilseed rape genotypes with the desired content of FA in oil similar to other significant parameters of quality (MÍKA et al 2003). NIRS method enables the analysis of intact rape seeds in an extremely short time without loss of their germination capacity.…”

“…A number of authors ( VAN DE VOORT et al 1992;WILLIAMS & SOBERING 1992;SATO 2002;MÍKA et al 2003) confirmed the suitability of NIRS (Near Infrared Reflectance Spectroscopy) as a non-destructive, rapid, cheap and relatively accurate method for determining the seed quality (content of glucosinolates, oil, proteins, dry matter and fatty acids) of oilseed crops. In all measured components including FA high significance of the correlation between NIRS and the reference method (GC) was found (VELASCO et al , 1999a.…”

Based on NIRS (near infrared reflectance spectroscopy) measurements carried out in a collection of 262 samples of winter oilseed rape with a different content of fatty acids (FA) in oil, calibration equations for the laboratory instrument Foss-NIRSystem 6500 were developed. Calibration was focused on the possibility of screening seed samples of different composition of oleic acid (C18:1), linoleic acid (C18:2) and linolenic acid (C18:3) using NIRS analysis. The reference method was gas chromatography (GC). The content of FA in segregating F<sub>2</sub> generations after crossing between lines with different contents of FA and lines with standard content of FA in oil ranged from 32.3 to 82.0% for C18:1, 10.2–26.8% for C18:2 and 3.3–11.8% for C18:3. The verification of a validation equation in 50 randomly selected samples of F<sub>2</sub> generation in the year 2006 proved high correlation coefficients (r) between NIRS analysis and GC values, r = 0.86 for C18:1, r = 0.82 for C18:2 and r = 0.85 for C18:3. Non-destructive NIRS analysis enables rapid and reliable selection of materials with different composition of FA in the seed of oilseed rape (lines with desirable high content of C18:1 and low content of C18:3).

“…The FA compositions in seeds were determined by near-infrared reflectance spectroscopy (NIRS; Foss NIRSystems Inc., USA) using standard methods with three replicates (Mika et al, 2003). Seed oil content and protein content was determined by using nuclear magnetic resonance (NMR) (mq-20, Bruker, Germany) with at least five biological replicates according to Burns et al (2003) with modifications.…”

Oil bodies (OBs) are relatively simple but very important organelles comprising a matrix of triacylglycerol (TAG) surrounded by a phospholipid monolayer embedded and covered with unique proteins. The OB structure in Brassica napus with different oil content and the relationship between the oil content and the OB structure needs to be better understood. In this paper, the characteristics of OBs in the embryo of a series of B. napus materials with different oil content ranging from 34% to over 60% were studied. The results indicated that the OB size was significantly positively correlated with the oil content but was significantly negatively correlated with the glucosinolates and the protein content. Many genes associated with TAG synthesis, OB-membrane proteins, and the cell progress regulatory pathway were identified in the confidence interval of co-located QTLs for oil content, fatty acid (FA) compositions, and protein content. Our results suggested that the morphology of OBs might be directly controlled by the genes associated with OB-membrane proteins and indirectly controlled by the genes associated with TAG synthesis and cell progress regulatory pathway.

“…Ten main agronomic traits were measured in mature plants, including plant height, primary branch number, length of main inflorescence, number of siliques on the main inflorescence, number of siliques per plant, length per silique, number of seeds per silique, 1,000-seed weight, seed yield per plant, and seed oil content. Seed oil content was determined by near infrared spectroscopy (NIRS) using standard methods (Mika et al 2003).…”

The lobed-leaf character is a clearly recognizable morphologic trait in rapeseed (Brassica napus L.) that has potential advantages in hybrid production. The present study was carried out to analyze the effect of lobed-leaf trait on agronomic traits and to fine map the LOBED-LEAF 1 (BnLL1) gene in B. napus. The lobed-leaf line Yuye 87 and entire-leaf cultivar Zheyou 50 were used to produce four F 2 and eight BC 1 populations for genetic analysis. Multiple comparison analysis between lobed-leaf character and agronomic traits was carried out in two F 2 populations of reciprocal crosses between Yuye 87 and Zheyou 50. Results show that the lobed-leaf phenotype is controlled by a single an incomplete dominant gene and has no significant adverse effects on 10 main agronomic traits. The location of BnLL1 gene was narrowed down to a 36.7-kb homologous region of B. rapa between genes Bra009506 and Bra009511. On the basis of the annotation of orthologous genes in Arabidopsis, Bra009510 is considered to be a promising candidate for BnLL1 gene. The AT5G03790 is the orthologous gene of Bra009510 in Arabidopsis thaliana, with known functions in the formation of simple serrated leaves and in the suppression of bract formation. It is suggested that previously described lobed-leaf gene BnMOSAICLEAF (BnML) and the BnLL1 are the same genes controlling the lobed-leaf phenotype in B. napus, whereas the lobed-leaf gene BcLEAFLOBED 1 (BcLL1) is their homologue in Brassica campestris ssp. chinensis. These findings will facilitate the cloning and functional identification of the BnLL1 gene in future studies.
