Abstract
The papaya, Carica papaya L., is native totropical America and commercially cultivated throughout the tropical and sub-tropical regions of India. Propagation of papaya by seed is still the most commercial cultivation method. Generally, the number of male plants outnumbers the females in a plantation, which renders it unproductive. Growers are unaware of identifying the productive and unproductive plants at the nursery stage, So as to have male and female plants. The papaya is generally taken flowers within 75 to 150 days after transplanting. The gynodioecious varieties are preferred for commercial purpose, due to their high yield potential and occurrence of desirable types of sex expression among the flower types. So it is knowledge on selecting desirable papaya cultivars at the seedling stage that would help in raising the papaya orchard with the appropriate design.
