The purpose of this study was to determine the amount of
heterosis in three complex traits in barley and to investigate the
concept of component interaction as a means of producing heterosis.
The complex traits were grain yield, total leaf area, and malting
quality.
Seven varieties of spring barley were...
Response to heterosis for plant height, anthesis date, panicle
number, seed yield, and fall vigor rating was determined in a tall.
fescue group selected for diverse morphology, origin, and anthesis
date. Parents, single-cross progeny (SX), and first generation
selfed progeny (S₁) were included in the study.
Each experimental plot consisted...
