Modern aspects and tendencies of rapeseed productive and breeding progress

Бесплатный доступ

During the period since 2005 until 2010 the rapeseed sown area in Russian Federation had increased 3.5 times – from 244 thousand to 856 thousand hectares. Meanwhile the productivity of crop remained invariable – 1.0-1.1 thous./ha. One of the important elements of strategy of receiving an economically attractive yield of rapeseed is the use of modern high productive varieties and hybrids. Inbred varieties of Russian breeding do not concede on productivity to foreign varieties and occupy an in-termediate position between hybrids and varieties-populations. Rapeseed hybrids have an advantage before the varie-ties – the ability of stable realization of the inherent potential of productivity in various conditions. Inbred winter rapeseed varieties of VNIIMK breeding – Elvis, Loris, Meot and Accent are characterised by potential seed yield of 4.5-5.0 thous./ha, that is on average 15-20 % higher, than in varieties-populations.
