Шокирующе, немыслимо и грустно!

Путинская Россия воюет с Украиной, захватывая ее. Это было невообразимо еще несколько дней назад, но это так.

Пожалуйста, помогите нашим украинским друзьям всем чем можете.

Эта просьба адресована также всем нашим друзьям-пчеловодам в России и нашим друзьям-пчеловодам в Беларуси.

Помогите украинцам!

Ваша команда Фонда Карла Керле

=============================================================================

Shocking, inconceivable and sad!

Putin's Russia is overrunning Ukraine with war. Unthinkable until a few days ago, but still a sad truth.

Please help our Ukrainian friends with all the possibilities you have.

This request goes expressly also to all our Russian beekeeper friends and our beekeeper friends in Belarus.

Help the Ukrainians!

Your Karl Kehrle Foundation Team

=============================================================================

Erschütternd, unfassbar und traurig!

Putin's Russland überzieht die Ukraine mit Krieg. Bis vor wenigen Tagen undenkbar und trotzdem traurige Wahrheit.

Bitte helft unseren ukrainischen Freunden, mit allen Möglichkeiten, die ihr habt.

Diese Bitte geht ausdrücklich auch an alle unsere russischen Imkerfreunde und unsere Imkerfreunde in Weißrussland.

Helft den Ukrainern!

Ihr Karl Kehrle Foundation Team

=============================================================================

Bouleversant, inconcevable et triste !

La Russie de Poutine envahit l'Ukraine par la guerre. Impensable il y a encore quelques jours, et pourtant tristement vrai.

S'il vous plaît, aidez nos amis ukrainiens avec tous les moyens dont vous disposez.

Cette demande s'adresse aussi expressément à tous nos amis apiculteurs russes et à nos amis apiculteurs de Biélorussie.

Aidez les Ukrainiens !

Prof. Dr. Dietrich Klakow [Breeding value estimination and calculation of Coefficient of Inbreeding]

This page provides predicted coefficients of inbreeding (COI) when mating a breeder colony (mother) with a drone colony in 2022.

You can search by name of the planned mother colony and year of birth of the queen of the mother colony. In case the name is part of an anonymous queen (e.g B466(FF)) and the year of birth is the previous year (in 2022 this would be .21) also mating partners for anonymous queens (e.g. that have B466(FF).21 as a parent) are displayed.

If there are multiple hits for the same search, multiple tabs are displayed, one for each possible mother colony matching the search. By clicking on a tab, you can select a mother colony.

Queen bee COI child colony: as the queen of the child colony is a sister of the workers of the mother colony, the queen's coefficient of inbreeding is identical to the coefficient of inbreeding of the workers of the mother colony and cannot be influenced by mating in 2022. This is the COI displayed in the corresponding tabs.

Below the tabs you see the results for the different possible drone colonies. By clicking on the red arrow, you can sort the table by increasing/decreasing COI.

Worker bee COI child colony: the inbreeding of the workers depends on the type of mating. Single Drone Insemination (SDI) resulting in the highest COI, Multiple Drone Insemination (MDI, all drones from the same colony) in a moderate COI and a mating station in the lowest COI. Of course in any case the COI of the parents and their relatedness has overall a very big effect.

By clicking on the “show” button, the full pedigree of queen and drone colonies and their evaluation are displayed.

Note: this is available only for colonies which have been added to the pedigree before January 1st 2022. Updates can be provided in monthly intervals.

We follow the approach by Bienefeld et al. 2007 https://www.apidologie.org/articles/apido/pdf/2007/01/m6058.pdf and Bienefeld et al. 1989 https://www.apidologie.org/articles/apido/pdf/1989/05/Apidologie_0044-8435_1989_20_5_ART0009.pdf

A breeding value of 100 means that 50% of the queens are better than all queens, 50% are worse. 110 means the queen is better than 84% of all queens. For 120 the queen is better than 98% of all queens.

Last year, the breeding values were normalized with respect to the average evaluation. This year, the breading values are normalized as in beebreed.
