Variation in chlorophyll content in barley mutants

A field study was conducted to investigate variation in chlorophyll content in barley mutants. A significant decrease in chlorophyll content was observed in the chlorina mutant compared to parent while in most of the other mutants there was significant increase. The individual values of chlorophyll a and chlorophyll b revealed interesting trends. In the mutants, an increase in the chlorophyll a content had been associated with a decrease in chlorophyll b content. The dwarf mutant with variable chlorophyll pattern from that of parental control could be of greater use in developmental studies. Correlation studies revealed a positive association of grain yield with total chlorophylls and flag leaf area.
