Testing of fig varieties on highland

Abstract

     The purpose of this research was determined the satiable of fig varieties for cultivating in highland. Five fig varieties; Dauphine, Japan, Verte, Variegated, and Brown-turkey were grown at Chiang-Mai Royal Agricultural Research Center (CMRARC), 1,300 meters above sea level. After the fourth year (2012-2015), Variegated had the highest annual increase in trunk circumsference growth. The average annual increase of Variegated trunk circumference was 2.4 cm/year, followed by Japan, Dauphine, Verte, and Brown-Turkey which were 2.0, 1.7, 1.3 and 1.0 cm/year, respectively. Japan showed the highest average yield per plant, 50 fruits. While Verte, Dauphine, Variegated, and Brown-Turkey showed average yield of 35, 33, 20 and 5 fruits plant respectively. Mature fruit results indicated that Brown-Turkey had the highest average fruit weight (65.5 g/fruit). This followed by Japan, Dauphine and Verte, 42.9, 35.4 and 33.6 g/fruit. respectively Variegated variety had produced the smallest fruit at 20.46 g/fruit. Japan variety had the highest total soluble solids at 12.3 brix, followed by Variegated, Brown-Turkey and Verte varieties with total soluble solids as 11.9, 11.5 and 9.65 oBrix respectively. Dauphine has lowest dissolved solids at 8.94 °Brix. Overall, Japan variety are more suitable for highland planting than other varieties in this trial.
