Not so long ago, only cucumber varieties that were pollinated by bees were grown in the open ground. Such cucumbers are distinguished by their amazing taste, they can be salted and pickled. But gradually they began to be replaced by self-pollinated varieties of cucumbers for open ground (parthenocarpics), or self-fertile F1 hybrids. Their fruits can be tied without pollination by bees. Initially, such varieties were invented for closed greenhouses, but, as it turned out, they give a high yield, growing on open land.
Partenokarpiki - self-pollinated cucumber varieties for open ground
These cucumbers have undeniable advantages. Self-fertile hybrids are characterized by extremely high productivity and quality of green stuff. Their fruits taste great without bitterness. Fruiting occurs continuously, and the plant itself is resistant to the most harmful diseases and adverse climatic conditions. Given the fact that bee populations are becoming smaller every year, self-pollinated varieties of cucumbers for open ground have become a real find for all gardeners and field breeders. In addition, during the period of mass flowering of cucumbers, the weather is often cool, and then gardeners encounter a problem: there are plenty of flowers, but there is no ovary. Therefore, high-yielding varieties of cucumbers for open ground, self-pollinated, are currently the most popular in modern vegetable growing.
Hybrid F1 Zador
Not so long ago, domestic breeders bred a parthenocarpic hybrid, which has not only wonderful taste, but is also great for pickling and pickling. F1 Zador is classified as a gherkin type hybrid, to the group “early varieties of cucumbers self-pollinated for open ground”. This species is characterized by high productivity. The fruits of the cucumber are tasty, without bitterness, dark green in color, with large tubercles and whitish pubescence. The shape of the fruit is cylindrical, up to 10 cm long. It is these cucumbers that are considered the most successful option for pickling. The skin is rather thin, which contributes to the good penetration of salt. Seeds in these hybrid cucumbers are absent, so that there is no void inside the salting.
Early varieties of cucumbers self-pollinated for open ground Zador are grown both by direct sowing in open ground and through seedlings. The plant is extremely resistant to disease, rot and weather. The stem branches well. The lashes of the cucumber are half open, the leaves are medium in size, which ensures convenient fruit collection.
Self-pollinated varieties of cucumbers for open ground F1 Picas
These vegetables are mid-season varieties: it takes about 55 days from germination to obtaining fruits. The plants are very powerful, with a long main shoot. The hybrid has an average shoot formation ability. These cucumbers can be grown in greenhouses or open ground, after holding the plants for a while under the film. In early May, you can sow seedlings. When two or three true leaves appear, the plant is planted in the ground. This usually happens in May-June. When landing, it is better to use a 40 x 40 pattern.
The fruits are dark green in color, have a cylindrical shape and reach 20 cm with a mass of 180-220 grams. In each node of the plant, up to three ovaries are formed. The hybrid is quite resistant to rot and powdery mildew. This variety has a high yield. Taste is excellent. Poor for salting.
Hybrid Raphael F1
Self-pollinated varieties of cucumbers for open ground F1 Rafael are mid-season hybrid species with a period of 50 days from seedling to fruiting. The length of the main shoot can reach 3-3.5 meters, while the shoot formation is average.
The hybrid is more suitable for greenhouses, however, seedlings are also planted in the ground. Sowing seedlings can be done in early May, and direct planting in the ground - at the end of the month. The length of the green stuff reaches 20 cm. In this case, the fruits have a dark green color. Taste is high. Up to two ovaries can form in one node. Fruits are not suitable for salting. The plant is resistant to root rot and various diseases.
White Angel F1
Hybrid White Angel F1 refers to mid-season varieties with a very high degree of parthenocarpy (self-pollination). Type of flowering - mixed. The variety is intended for both growing in greenhouses and in open ground (subject to the temporary use of a protective film).
The plant has a high degree of shoot formation. In the sinuses of each leaf, up to two ovaries can form. The color of the cucumber is unusual - green and whitish. Fruits reach 8 cm in length and have infrequent tubercles. Fruits can be consumed both fresh and pickled or canned. Productivity from one bush is up to 4 kg.
Caring for self-pollinating hybrid cucumbers
To obtain high germination of seeds, it is necessary to maintain a temperature of at least 13 degrees Celsius. The ideal temperature for seed germination is 18 degrees at night and 24 degrees during the day.
Therefore, self-pollinated high-yielding varieties of cucumbers for open ground (Rodnichok and other bee pollinated varieties similarly) should be sown when the soil is properly warmed up. The bed should be located on the sunny side and be protected from the wind. Sowing is mulched with humus a little, and then cover with a film protection to protect the soil from drying out.
In the case of planting seedlings, you can expect a crop 2-3 weeks earlier than when sowing seeds. When breeding seedlings, it is better to use a special substrate, in large quantities containing horse peat.
Top dressing cucumbers should be done carefully, under the root, using low-concentration water-soluble mineral fertilizers once a week. Water for irrigation should be at room temperature.
