Evaluation of biological progress in rapeseed ([i]Brassica napus[/i] L.) breeding
Journal Title: Rośliny Oleiste - Oilseed Crops - Year 2013, Vol 34, Issue 2
Abstract
The aim of the present paper was the evaluation of biological progress in winter rapeseed breeding. The material for investigations consisted of the data obtained from registration and post registration trials conducted by Research Centre for Cultivar Testing (COBORU) in years 2001–2013 as well as preliminary and pre-preliminary trials with breeding materials of winter rapeseed of Polish Plant Breeding Companies Strzelce and Smolice. Considerable biological progress regarding yield of open pollinated as well as hybrid varieties has been observed. The yielding ability of hybrid varieties was higher by about 10%, as compared with yield of open pollinated varieties. Simultaneously, both types of varieties retain good seed quality – low glucosinolate content. Slow progress in the increase of fat content in seeds of new varieties was observed. Nearly 50% lower yield gained in production as compared to yield from postregistration trials indicated large possibilities of increasing of rapeseed seed production in Poland by better exploitation of yielding ability of varieties using optimal agrotechnic methods.
