PATH-COEFFICIENT ANALYSIS OF PYRTHRINS YIELD IN PYRETHRUM (CHRYSANTHEMUM CINERARIAEFOLIUM VIS) |
| Authors: | B.K. Bhat, R.C. Menary |
| Abstract:
Phenotypic correlation coefficients among several traits in pyrethrum have been reported. Path-coefficient analysis was used to determine the interrelationships between the pyrethrins yield (g/plant), economically the most important trait in pyrethrum, and four of its component characters. It was found that dry flower yield (g/plant) had the highest direct effect on pyrethrins yield followed by pyrethrins content (%) in the dry matter of the flowers. Flowers/plant, though positively correlated with flower yield, exerted a negligible negative direct effect on pyrethrins yield. Dry flower weight (g/100 flowers) also had a very small negative direct effect on pyrethrins yield. It has been suggested that pyrethrins yield can be effectively improved by selection of plants high in flower number and pyrethrins content. | |
