ABSTRACT

Presented results concerning 2 groups of research a) on quality assessment
of seeds belonging to 2 Polish and 5 foreign companies, offered on Polish market
between 2011–2013, b) on the effect of seed vigour on yield of beet roots.
This research was conducted between 2007–2013. The seeds of 58 sugar beet
varieties offered on the Polish market differed in vigour level among companies,
among varieties within a single company, and years of sale. The magnitude of
plant emergence in a phytotron 12 days after seed sowing time, in compost soil
(temperature 10ºC and moisture content 60% Fresh Water Content fluctuated
from 13.3 to 83.4% depending on the seed company. The speed of one plant emergence
estimated at the end of the emergence period oscillated from 11.43–14.25
days. According to the regression equation each 1% increment in a phytotron,
emergence increased the yield of roots by 0.247 t·ha -1. Low vigour of
seeds belonging to 5 companies decreased the potential yield by 5.3 to 17.2 t·ha-1
in relation to seeds of the 2 best seed companies. Each seed company is able
to offer seeds of the best quality on the Polish market. Sales of low quality
seeds is determined by the general sale policy of seed companies and methods
of Polish market treatment in comparison to another national seed market.

Key words: low temperature, emergence value, speed, spread.
