Prikaz eksperimentalnih hibrida kupusa (Brassica oleracea var. capitata L.)

Cabbage takes up significant area in vegetable sowing structure, and one of the factors of improving this production is adequate varieties selection. During the breeding process, experimental hybrids are tested in relation to currently grown varieties and hybrids in production. In this paper the characteristics of 18 cabbage genotypes are presented, out of which there are 9 experimental hybrids, 4 varieties and 5 hybrids from broader production. Cabbage genotypes in the trial are of differing length of growing season, as well as differing head weight. Properties variability analysis was performed using PCA method, where two main components were chosen based on screen test, and these were used to define 57.7%. Head weight and head diameter are properties based on which the tested hybrids were graded into quantitatively different groups.Kupus zauzima značajne površine u setvenoj strukturi povrća, ijedan od faktora unapređenja ove proizvodnje je odgovarajući sortiment. Tokom procesa oplemenjivanja ispituju se eksperimentalni hibridi u poređenju sa aktualno gajenim sortama i hibridima u proizvodnji. U ovom radu su prikazane karakteristike 18 genotipova kupusa, (9 eksperimentalnih hibrida, 4 sorte i 5 hibrida iz šire proizvodnje). Genotipovi kupusa u ogledu su različite dužine vegetacije, kao i različite mase glavice. Analiza varijabilnosti osobina vršena je PCA metodom, gde su na osnovu scree testa, odabrano dve glavne komponente kojima je prvom definisano57.76% varijabilnosti a drugom 41.86%. Masaglavice i prečnik glavice su osobine na osnovu kojih su ispitivani hibridi razvrstani u kvantitativno različite grupe
