Mode of inheritance of yield and yield components in cabbage (Brassica oleracea var. capitata L.)

Abstract

Used in this study were seven divergent cabbage cultivars, which we crossed using the complete diallel cross method. The traits we analyzed are important for further selection and were actually chosen based on this. The study's results showed the traits to be significantly divergent, which represents a significant source of variability for the next cycle of selection. The predominant mode of inheritance of head mass and the edible portion of the head was superdominance. Variation of these two traits was prominent in both the parents and the hybrids, the primary reason being the differences in earliness of maturity. Yield once again proved to be a complex trait, varying in the parents and the hybrids alike. The variability of yield was much larger in the hybrids than in the cultivars. Superdominance occurred 23 times.

Sedam divergentnih sorti kupusa, dobijenih metom potpunog dialelnog ukrštanja, korišćeno je u ovom istraživanju. Analizirana svojstva su važna za dalju selekciju i stoga su i izabrana. Dobijeni rezultati pokazuju da su svojstva značajno divergentna što predstavlja važan izvor varijabilnosti za sledeće cikluse selekcije. Superdominantnost je prevashodni način nasleđivanja mase glavice i jestivih delova glavice. Variranje ova dva svojstva bilo je značajno kako kod roditelja tako i kod hibrida što je i osnovni razlog razlike u ranostasnosti. Prinos se još jednom pokazao kao složeno svojstvo, koje podjednako varira kako kod roditelja tako i kod hibrida. Varijabilnost prinosa bila je mnogo veća kod hibrida nego kod kultivara. Superdominantnost se javila 23 puta.
