Thirty-eight varieties entered the list of recommended sugar beet varieties in the year 2016. In the tests, seeds treated with Cruiser Force preparation were used exclusively. The weather conditions were favorable for sugar beet growth in the beginning but in the subsequent months, weather conditions at the individual locations differed. The root yield and sugar yield values did not differ sig-nificantly from last year’s values. The list of recommended sugar beet varieties is published every year by the Central Institute for Supervising and Testing in Agriculture (ÚKZÚZ) commissioned by the Ministry of Agriculture of the Czech Republic. Those who take part in the pro-cess are Sugar Beet Growers Asso-ciations, sugar companies and seed firms. The varieties are divided and evaluated according to their tolerance. The overall indicator, the INDEX, expresses parameters of a variety in relation to the average of the whole tested assortment on a relative scale. The list of recommended varieties includes not only one-year results, but also the results of two and three-year tests. Results from locations with beet cyst nematode infestation are shown in separate tables. © 2017, Listy Cukrovarnicke a Reparske. All rights reserved.

In the year 2016 sugar beet trials from four locations were assessed for the purpose of registration. Sugar beet varieties are registered after a three-year testing based on the index values reached in treated or untreated variety. The index is the overall indicator that expresses parameters of a variety in relation to the average of the whole tested assortment on a relative scale. The average index value was 101.5 in both varieties; in the varieties with higher resistance to beet cyst nematode, the index value of 100.5 was sufficient. To register the varieties after a two-year testing, the index value must be at least 102.0 in each year and variety. Based on the registration tests result, 8 sugar beet varieties were registered this year; 4 conventional (Torero, Mercedessa KWS, Honey, and FD Bobsleg) and 4 varieties with increased resistance to beet cyst nematode (Libuše, FD Taekwondo, Lumen, and Přemysl); the varieties are of N and NV types. © 2017, Listy Cukrovarnicke a Reparske.

Forty-one varieties entered the list of recommended sugar beet varieties in the year 2013. In tests, seeds treated with Cruiser Force preparation were used exclusively. Weather conditions were different than in past years, extreme humidity was replaced by high temperatures without rainfall. This was the cause of increase in tuber weight and decrease in sugar content The list is published every year by the Central Institute for Supervising and Testing in Agriculture (ÚKZÚZ) commissioned by the Ministry of Agriculture of the Czech Republic. Those who take part in the process are Sugar Beet Growers Associations, sugar companies and seed firms. The testing replaces the former system of United testing of registered sugar beet varieties (existing since 1993). Leaf diseases, yield, sugar content, sugar yield etc. are evaluated. The overall indicator, the INDEX, expresses parameters of a variety to the average of all tested assortment on a relative scale. The varieties are evaluated independently within the same tolerance. SDO lists not only the 2013 results, but also the two- and three- year long evaluation results. Results from Bezno and Lutín locality, where the beet cyst nematode appeared, are shown separately.

The INDEX is the overall indicator expressing parameters of a variety to the average of all tested assortment on a relative scale. 39 varieties entered the list of recommended sugar beet varieties in the year 2010. The number of varieties with special tolerance to rhizoctonia and nematodes increased. Therefore, the varieties of the same tolerance were evaluated independently. Not only the 2010 results, but also the two- and three-year long variety evaluation results are listed. Both qualitative and quantitative indicators have remained at roughly the same level as in the last year.

Thirty-nine varieties entered the list of recommended sugar beet varieties in the year 2015. In tests, seeds treated with Cruiser Force preparation were used exclusively. The weather conditions differed from the previous years; in the beginnning the conditions were favorable for sugar beet growth but since June the temperatures were extremely high without precipitations which had a negative impact on the root weight.

Thirty-eight varieties entered the list of recommended sugar beet varieties in the year 2014. In tests, seeds treated with Cruiser Force preparation were used exclusively. Weather in 2014 was favorable for sugar beet development, which also demonstrated by an above-average bulb yield (by 14 t.h–1 in average), average sugar content decreased by 1%.

The tests were based in seven localities on two systems of cultivation: with and without fungicidal treatment. Average yields were about 8 t ha-1 lower than in 2014 and sugar content reached 19%. To get registered it is necessary to reach an overall indicator "index" of min. 101.5 in at least one system of cultivation after three years of testing; after two years of testing in case of standard varieties as well as the ones immune to beet-cyst nematode, the index must be min. 102.0 in both the test-years in the same variety. Based on the results of registration tests 19 new sugar beet varieties will be entered into the Czech Directory of Varieties in 2016; 13 varieties are standard and 6 are immune to beet-cyst nematode, mostly type N and NV. © 2016, Listy Cukrovarnicke a Reparske.

The tests were based in six localities and on two systems of cultivation; with and without fungicidal treatment. Yields in some localities reached more than 100 t.ha-1 and average sugar content 18 %. To get registered it is necessary to reach an index of min. 101.5 in at least in one system of cultivation after three years of testing; in two-year testing of standard varieties as well as the ones immune to beet-cyst nematode, the index must be min. 102.0 after both the test-years in the same variety. Fourteen new varieties will be entered into the Czech Directory of Varieties in 2013; nine are standard and four are immune to beet-cyst nematode, mainly normal-type to yield type.
