| Abstract: | Lines of winter hexaploid Triticale and their F1 and F2 hybrids differing in morphological structure, pigment contents, photosynthetic productivity, and grain crops were studied. F1 hybrids received by crossing of Triticale lines contrasting in pigment contents showed in some cases a heterosis effect for chlorophyll (Chl) content per unit leaf area. Variation analysis demonstrated a polygenic control of Triticale pigment contents, and different rate of increase in F2 generation. We found maternal type of heritability of Chl b content and Chl content in light-harvesting complex of photosystem 2. |
