The potential of canola quality (Brassica napus L.) as a new winter oil crop in Egypt

摘要

The spring types of B. napus L. could be grown successfully under winter season in Egypt. Some genotypes of canola mainly were introduced from abroad were evaluated since 2002- 2005 at the Experimental Station of National Research Center at Shalakan, Qalubeia Goveronorate, Egypt. Seed yield (kg./acre), as well as, yield attributes of some canola genotypes were significantly different, except number of seeds / pod and 1000 - seed weight were insignificant. AD201 and also Pactol cvs were surpassed in their yields, while Import 62 and 196 cvs yielded the lowest seed yield. Seed yield / plant (g.) was increased in AD201, Silvo and Serw 6, while the lowest was recorded at Pactol or Import 62 genotypes. Oil percent and also oil yield (Kg./acre) were significantly different in canola genotypes. The highest oil percent (43.81) and also oil yield (487.806 Kg. / acre) were obtained by AD 201 cv., while the lowest was recorded at Import 196.Fatty acid composition of canola genotypes used were also different, Silvo and Serw 4 cvs had the highest palmitic acid, whereas, Pactol seem to be higher oleic and lower linolenic and erucic acids in comparison to other canola genotypes. At the same time, Silvo cv had the lowest oleic and highest linoleic and linolenic acids, whereas Serw 6 recorded the highest erucic acid (2.66%) compared to other canola genotypes.
