VARIETAL FEATURES OF PROMISING VARIETIES OF REPAIR RASPBERRIES IN THE SOUTH-EAST OF KAZAKHSTAN

Abstract

As a result of a two-year study of the biological characteristics of seven introduced varieties of remontant raspberries, in the conditions of the south-east of Kazakhstan, the main economically useful features of Russian and Polish varieties were established. The Russian cultivar Bryanskoye Divo 9.8 t/ha was the most productive, exceeding the other studied cultivars by an average of 12%. For productive varieties Polka by 4.2%, this variety is distinguished by the largest berries (average weight - 5.2 g). Research will be continued and, based on their results, promising varieties will be submitted to the SSI. The experiments were carried out in the farm "Aidarbaev", in the village "Saimasay", Enbekshikazakh district of Almaty region. In the first half, studies were carried out, with positive weather conditions. The second half of the growing season was characterized by significantly hot, dry-dry weather. The repetition of the experiment is 3-fold for 10 accounting plants, in each repetition. Phenological records of observation were carried out during the growing season. So, with a naturally simultaneous beginning of the growing season, observed at the end of March, shoots appeared in the remaining phases, which differed in terms of their passage. In the experiment produced, counting the leaves. Despite the longest shoots of the Karamelka variety, in terms of the number of leaves, it is inferior to the Raspberry Ridge and Nizhegorodets varieties. In the Polana variety, all the main biometric indicators were lower than in the other studied varieties.
