Aspects of the analysis of spring barley hybrids obtained by crossing two-rowed with six-rowed varieties

Aspects of the analysis of spring barley hybrids obtained by crossing two-rowed with six-rowed varieties

Sibirskii Vestnik Sel' skokhozyaistvennoi Nauki ( 2): 23-28

A study was made of F1 and F2 hybrids from topcrosses with the 2-rowed testers Dneprovskii 435, Erofei and Pervenets, each crossed with the 6-rowed Conquest. Problems in analysis of the genetic variance for yield-related traits are examined, and data are presented on combining ability for these traits. Grain weight/ear showed overdominance (heterosis) in Dneprovskii 435 X Conquest and Pervenets X Conquest and complete dominance of the 2-rowed parent in the cross Erofei X Conquest.
