Abstract

A joint regression analysis for weight and number of nuts in arecanut was conducted. Significant differences between varieties as well as between years for weight of nuts were observed. The regression coefficients of the varietal means ov.r year means in most cases were significant. Differential response to varying environmental values was observed between the varieties. The highest yielding varieties ‘VTL. 11’, ‘VTL. 17’ and ‘VTL. 29d’ were found to be suitable for planting under favourable environments only, ‘VTL. 12’ and ‘VTL. 29a’ with fairly high yield showed stability in performance also.
