Abstract

Investigations were carried out on the characters: height of the stalk without inflorescence, number of leaves per stalk and green mass yield per stalk in the following parental genotypes: Prilep (P 12-2/1), Pobeda 2 (P-2), Yaka (YV 125/3) and Forchheimer Ogrodowni (FO) and their hybrids obtained with diallel crossing in F1. F2, BC1 (P1) and backcross reciprocal, BCl. (P2 ) generation. The application of diallel analysis leads to a better knowledge of the genetic character of parents and their hybtids. The aim of these investigations was, through genetic components of variance for F1, F2, BC1 (P1) and BC1 (P2) generations, to get a better knowledge on the inheritance of quantitative characteristics. Investigations have shown that the additive variance is prevailing in inheritance of the three characters in generations studied. The interaction between additive and dominant genes for the characters height of the plant and number of leaves per stalk in BC1 (reciprocal) generation is different than in other generations, whereas for green mass yield the interpretation is the same in all generations. The ratio of the total number of dominant and recessive genes in BC1 (reciprocal) generation differs from other generations regarding the first two characters, whereas for the green mass yield per stalk all generations have identical interpretation. The heritability is very high, which means that the characters investigated are highly inheritable.
