Padma lay, G. V. Basvaraju, G.Sarika and N.Amrutha

To know the optimum fruit maturity stages, ideal temperature and media, dormancy breaking methods on seed quality parameters of papaya (Carica papaya L.) cv. Surya. Seeds extracted from fruits harvested at 1/4th1/2 th,3/4th and Complete yellow/orange and after ripening were subjected to dormancy breaking treatments, the result revealed that higher germination was recorded in GA3 @ 300ppm for 12 h and KNO3 @ 2% for 24 h (93.00 and 91.00% respectively). Bio inoculation of Azotobacter chrococcum for 20 days and Hot water soaking @ 50°C for 45 min recorded maximum germination respectively ( 92.50 and 78.00%), SVI (1387 and 969) field emergence (81.30 and 59.33%). Thus, Seed extraction from complete yellow/orange fruits, GA3, KNO3 and Azotobacter chrococcum treatments can enhance the germination and other seed quality parameters in papaya (Carica papaya L.) cv. Surya.
