Evolution of Induce and Physical Mutagen on Vegetative Traits of Papaya (Carica papaya L.)

Abstract

The experiment was conducted on Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, located in Meerut, Uttar Pradesh. The experiment was laid out in RBD design and data was recorded on different growth trait of papaya.  Two variety of papaya Arka surya and Coorg honey dew, the seed of papaya was treated with Gamma and EMS mutagen and sown in field for evolution. The treatment detail of the experiment was T1, 5 Gy, T2, 10 Gy, T3, 15 Gy, T4, 0.25% EMS, T5, 0.50% EMS, T6, 0.75% EMS, T7, 5 Gy+0.25% EMS, T8, 10 Gy+0.50% EMS, and T9, 15 Gy+0.75% EMS. Finally, on the basis of result recorded that in both year days taken to seed germination and stem girth(cm), 10GR better performance over all treatment, while in number of leaves at flowering and petiole length (cm), 5GR better performance over all treatment. Whereas, In EMS and (Gamma rays + EMS), 0.25% EMS and 5G+0.25%EMS perform better result for petiole length and number of leaves at flowering while for days taken to seed germination and stem girth, 0.50%EMS and 10G+0.50%EMS perform better result.
