Recently, on packages of seeds, you can often find the inscription - "parthenocarpic hybrid"? What does it mean? What is the difference between bee-pollinated and parthenocarpic varieties and hybrids?

What is the difference between parthenocarpic and bee-pollinated cucumber hybrids?

On plants of bee-pollinated varieties and hybrids, male and female flowers are always present. For the formation of zelents, it is necessary that pollen from male flowers gets on the female flowers. In nature, bees, bumblebees and other insects help us in this. For those who like to grow bee-pollinated varieties and hybrids of cucumber, we recommend sowing and planting them not in greenhouses, but in open ground. If, due to weather conditions, the flight of insects is impossible, and the female flowers are formed, then due to the lack of pollination, the ovaries will turn yellow and disappear. Bee-pollinated cucumber hybrids Perseus F1, Dasha F1, Diana F1, Aristocrat F1 form a large number of female flowers, which makes them simply irreplaceable in the garden, when growing cucumbers in the open field.

Parthenocarp (from the Greek Parthenos - "virgin" and karpos - fruit; literally "virgin fruit") is a special case of parthenogenesis, virgin fertilization without pollination in plants, usually with the formation of fruits without seeds. Fruits that form with parthenocarpies are either seedless or contain “empty” seeds without embryos. There are two types of natural parthenocarpies. In the first case, the process of pollination is completely absent, in the second, the cause of the formation of the fruit is the irritation of the stigma of the flower with its own or someone else's pollen.

The ability to form parthenocarpic fruits in cucumber plants is due to the genetics of the variety and / or hybrid. Parthenocarp in cucumber plants is complete, when all flowers give seedless fruits, or partial. According to the manifestation of this trait, varieties and hybrids are divided into several groups: with weak, medium, and strongly pronounced parthenocarp. At the same time, the nature of inheritance of parthenocarp in cucumber plants is complex and largely depends on growing conditions. The study of the influence of temperature, day length and light intensity on the parthenocarp showed that the optimal temperature regime for better setting of cucumber fruits is to maintain a temperature of 23 ° C during the day and 17 ° C at night.

Due to their unique ability to set fruits without pollination, parthenocarpic hybrids are in increasing demand among the population and cucumber producers, as they are better suited for growing in unfavorable climatic and seasonal (weather) conditions. It is also recommended to plant them in greenhouses and film shelters, where tying greens does not depend on pollinating insects. Therefore, early cultivation of hybrids Bastion F1, Ladies' saint F1 and Emerald placer F1 with a strongly pronounced parthenocarp and the ability to form more than 3–6 ovaries in the nodes, allows obtaining high yields regardless of unfavorable growing conditions. Parthenocarpic hybrids for salad purposes Crunchy slice F1 and Khrustlyandiya F1 have juicy and sweet flesh without seeds.

There is a popular belief that parthenocarpic hybrids cannot be used for homemade preparations. At present, the breeders of the POISK Agroholding have created a number of multipurpose hybrids, the fruits of which are intended both for fresh consumption and for pickling and salting: Atos F1, Damskiy spleen F1, Stilyaga F1, Forsage F1.

Benefits of parthenocarpic cucumber hybrids:

  • consistently yield a harvest regardless of the presence of pollinating insects and unfavorable weather conditions for the growth and development of cucumber plants;
  • fruits without seeds and without bitterness;
  • greens are the same size, color and are aligned in shape;
  • they can be grown both in open ground and in greenhouses, hotbeds and on balconies;
  • retain their attractive appearance, density, juiciness and taste for a long time;
  • have amicable continuous fruiting;
  • most have a bouquet arrangement of ovaries in a knot, which is the key to a high yield;
  • resistant to the most common diseases of cucumber plants.
