Shows the impact intsuhtu the formation of the stem height, number of pods on the main inflorescence, pod length and number of seeds in a pod in different genotypes of winter rape. We found that most samples observed inbreeding depression. Comparing plant height stem, which were obtained from the seeds, which was formed with the free pollination and plants ( I1) - from seeds obtained by selfing compulsory, it should be noted that all samples had lower height of the stem plants I1 compared with open blossoms . Most clearly apparent inbreeding depression in grade Trabant (Germany). The height of the stem in the first - generation intsuht was - 69,7 ± 3,2 cm, 20.2 cm smaller compared to the free pollination - 89,9 ± 2,2 cm. Significant reduction in the height of the stems of plants intsuht first - generation versus free plant pollination found in samples Landar ( Ukraine ) - 76,8 ± 3,6 cm, compared to 88,4 ± 2,7 cm Donhon - 79,4 ± 4,9 cm, compared to 90,2 ± 1, 1 cm Astrid (Germany ) - 87,9 ± 3,0 cm, compared to 99,8 ± 2,1 cm in the remaining researched samples observed weaker inbreeding depression and reduce the height of the stem varied in the range from 3.0 to 9,0 cm depending on the genotype of the variety ( hybrid ).

The impact of the first generation of the formation intsuhtu number of pods on the main inflorescence was different. There is both an increase and decrease in the formation of this trait in plants I1. Most clearly expressed in plant varieties depression Champion Ukraine - 13,4 ± 1,4 units. comparison of 24,9 ± 1,1 - plants for free pollination.

Significant reduction in the number of pods on the main inflorescence plants intsuht first - generation versus found in samples Donhon - 20,8 ± 2,8 units. Versus Nadia - 20,2 ± 1,3 pcs., Compared to 28.2 ± 2,1 pcs., Astrid - 17,4 ± 2,2 units. compared to 25,5 ± 1,4 units. and Landar - 24,8 ± 2,1 units. compared to 27,4 ± 2.0 pc.

In samples Champion Ukraine, Donhon, Vectra, Astrid intsuht the first generation of a decrease in the length of the pod. Most clearly apparent inbreeding depression in grades Champion Ukraine and Vectra. The length of the pod in the first - generation intsuht grade Champion of Ukraine was 5,9 ± 0,2 cm, compared to 7,1 ± 0,2 cm, grade Vectra - 6,6 ± 0,3 cm, compared with 7.5 ± 0,2 cm.

One of the main structural elements of performance is the number of winter rape seeds in pods. Of the 10 subjects in seven samples, an increase in the number of seeds in a pod in plants intsuht first - generation compared with open blossoms.

Depression of this trait in plants (I1) versus free plant pollination found only in grade Champion Ukraine - 25,4 ± 1,1 units. comparison of 27,4 ± 0,7 pcs., Anna - 27,7 ± 3,5 units. comparison of 28,9 ± 1,5 pcs., Kronos - 20,6 ± 1,9 units. comparison of 21,0 ± 1,1 units.

Established that intsuht the first generation affects the formation meromes and accompanied by depression, in which different genotypes of winter oilseed rape reduces the height of the stem ( to 20.2 cm), number of pods on the main inflorescence (up 11.5 pc.), Pod length ( to 1.2 cm), number of seeds in a pod (up to 2.0 pc.) compared to autbrydynhom. Top incompatibility height stems found in a variety Trabant, Donhon, Landar, the number of pods on the main inflorescence found in variety Champion Ukraine, Donhon, Astrid, Nadia for pod length and number of seeds in a pod - Champion of Ukraine.

We need to continue research in the next - generation intsuht to identify and create a collection both incompatibility and winter rape compatibility lines for further breeding.
