SU1421276A1 - Method of hybridization of grape - Google Patents

Abstract

The invention relates to agriculture and can be used in the selection of grapes. The purpose of the invention is to increase the efficiency of hybridization by increasing the excretory functions of the stigmas of the paternal pistils. In the spring of plants of hybridized varieties, the bases of green shoots are spudded with earth, and in the autumn they are separated from the uterine bush, tied in bunches and placed for storage. After storage, the plants are planted in growth vessels for growing. During the period of hybridization, maternal and paternal plants establish a series. Seven days before flowering, the inflorescences of the mother plant are castrated and placed in isolators along with the inflorescences of the father plant, part of the shoots with leaves located above the node following the node bearing the hybridized inflorescence of the father plant are removed before. This method allows to obtain from 74.8 to 1 10.8 seeds per inflorescence. cl

The invention relates to agriculture and may be used in planting and farming.

The aim of the invention is to increase the efficiency of hybridization by increasing the excretory functions of the stigmas of paternal plant pestles.

Example /. Tests of the proposed method were carried out during the hybridization of single varieties and Kishmish Moldavian.

Individual plants of hybridized opts were obtained as follows. and during the autumn pruning, an additional 2-3 knots with two winter eyes on each were left on the bush head during the autumn pruning. In the spring, when growing shoots reached 0–50 cm, the head of a bush and the base of green shoots that grew 10–15 cm from knots, was tucked into a mound of earth. In the autumn, before pruning a collection vineyard, the mounds of the earth were removed, and the shoots grown on the knots were separated from the uterus together with the root system developed on their basis. The resulting rooted vines were cut to a length of 1.5 m, bundled and placed in storage in the basement in sand.

In October, the rooted vines of hybridized varieties were removed from storage, rolled into a ring and planted into vegetation vessels so that the three hibernating ocelli pre-waxed above the soil surface remained and installed in the greenhouse for germination, where relative humidity was maintained 75-80%, the length of the light period in days is 14 hours, during which the air temperature was maintained at 27-30 ° C, and at night to 18-21 ° C. In December, plants of hybridized varieties were established in close proximity to one another. They were ready to bloom. Seven days before the bloom, the inflorescences of the mother variety Codri nka were neutered and placed in isolators along with the inflorescences of the father variety Kishmish Moldavian. A part of the shoot with leaves, located above the node following the node bearing the hybridized inflorescence of the father plant, was removed. Insulators were shaken daily for 10 days. On the growing season windows, accounting of the formed hybrid seeds was carried out. In crossbreeding took part 10 inflorescences of each variety. After harvesting the hybrid seeds, paternal varieties were cut shortly into three peepholes with the leaf surface removed. The shoots of plants of the mother variety are cut by 15 holes, rolled into a ring around the perimeter of the vegetative vessels and lees

pans of noMHeHiUjiM, substrate. Three were left above its surface (slopes. After 16 days, the plants of both varieties started a new vegetation and were roTOBi, by flowering in March. During the repeated hybridization, the crossed plants were interchanged with n pairs.

Seven days before the bloom, the inflorescence of the Codranka variety was neutered and placed in isolators along with the inflorescences of the variety KishmiSh Moldavian. A part of the shoot with leaves, located above the node following the node, bearing the hybridized inflorescence of the father plant, was removed. Insulators were shaken daily for 10 days.

At the end of the growing season, accounting of the formed hybrid seeds is carried out. In crossbreeding took part 10 inflorescences of each variety.

The effectiveness of the proposed hybridization method averaged in the first case 81.3 seeds, and in the second - 74.8 seeds per inflorescence.

Example 2. Individual plants of the Kishmish Moldavian variety were obtained as in Example 1. The rooted father vines were removed from storage in April, rolled into a ring and planted in vegetation vessels. The germination was established in open ground, and before flowering in close proximity to the bushes of the mother variety, Codri nka in the collection vineyard.

Seven days before the bloom, the inflorescence of the Codranca variety was neutered and placed in isolators along with the inflorescences of the variety Kishmysch Moldavian. The part of the plant with leaves located above the node following the node bearing the hybridized inflorescence of the father plant was removed. Insulators were shaken daily for 10 days. At the end of the growing season, accounting of the formed hybrid seeds was carried out. In the crossover, 10 social plants took part: tiy of each variety.

The effectiveness of the proposed hybridization method averaged 110.8 seeds per inflorescence.

Claims (1)
