Selection of Effective Issr-Primers for Genotiping of Cucurbitaceae Plants

Abstract

The article considers a new method of sowing in the early stages of barley breeding. The experimental research was carried out in 2017 in the Krasnoufimsky breeding center. Barley was used as the test culture for seeding. Methods of sowing that have been used were as follows: manual method (method «in the pipe») and the method with the use of the mechanized seeder SSFK-7. In the design of the sowing device SSFK-7, plastic funnels were added, which are located in the apparatus of batch sowing, snug against the blades of the cells. Plastic funnels are located evenly, so that the distance between them is the same, they move in a circle, which ensures the seeding of the seeds in portions, each being a line or a family. The seed tube that goes from the batching machine to the centrifugal seed distributor is disconnected, instead of it the branch pipe is connected to the cross, which distributes the seeds to two extreme right coulters, the other openers in this seeding method are not working. Analysis of the research results showed great practical value of the new method of seeding with the SSFC-7 seeder for the selection of breeding nurseries. The effectiveness of this method is characterized by a reduction in sowing time and labor intensity by 1,9 times. The improvement of the selection process and the replacement of manual labor with mechanized labor will make it possible to significantly increase the amount of selection in the future and to obtain high results in breeding.
