Abstract
1. Способ получения генетически чистых семян материнской формы для гибрида подсолнечника на принципе временной изоляции посевов в фазу их цветения от переопыления с другими формами подсолнечника, включающий посев семян в ранний по отношению к оптимальному для данного региона срок и выращивание растений сначала в защищенных по-сравнению с естественными для данного срока условиях, а затем в открытом грунте, отличающийся тем, что осуществляют посев семян стерильного аналога и закрепителя стерильности материнской формы гибрида в наполненные почвой рассадные горшочки, выращивают в них рассаду в отапливаемой теплице до фазы 2-х пар настоящих листьев, а затем ее высаживают в открытый грунт по схеме 6:2, где 6 рядов стерильного аналога чередуются с 2 рядами закрепителя стерильности, и выращивают в естественных условиях. ! 2. Способ по п.1, отличающийся тем, что выращивают рассаду в теплице при температуре 25-35°C. ! 3. Способ по п.1, отличающийся тем, что перед высадкой рассады в открытый грунт ее предварительно закаляют, постепенно снижая температуру и влажность воздуха в теплице. ! 4. Способ по п.1, отличающийся тем, что непосредственно при высадке рассады в открытый грунт проводят легкий полив растений.1. A method of obtaining genetically pure seeds of the mother form for a hybrid of sunflower on the principle of temporary isolation of crops in the phase of flowering from pollination with other forms of sunflower, including sowing seeds early in relation to the optimum period for the region and growing plants first in protected compared with natural conditions for a given period, and then in the open ground, characterized in that the seeds of a sterile analogue and the sterility fixer of the maternal form of the hybrid are filled cultivated seedlings, seedlings are grown in them in a heated greenhouse until the phase of 2 pairs of real leaves, and then it is planted in open ground according to the 6: 2 scheme, where 6 rows of sterile analogue alternate with 2 rows of sterility fixer, and grown in natural conditions. ! 2. The method according to claim 1, characterized in that the seedlings are grown in a greenhouse at a temperature of 25-35 ° C. ! 3. The method according to claim 1, characterized in that before planting the seedlings in open ground it is pre-tempered, gradually reducing the temperature and humidity in the greenhouse. ! 4. The method according to claim 1, characterized in that immediately when planting seedlings in open ground, light watering of plants is carried out.
