SESSION—III - PROPAGATION AND ROOTSTOCKS

Dr. J.P. Singh, Shri R.R. Kohli
For this Session, 17 papers were received and all the 17 papers were presented orally.

Dr. P.K. Majumdar presented the Keynote Address on ‘Recent Advances in Propagation and Rootstocks Research in Mango—World Situation’. He gave a very comprehensive account of the research work conducted till date and achievements made under different methods of propagation under different agro-climatic regions of the world. He gave a detailed account of veneer grafting, stone grafting and stooling in mango and mentioned that instead of using a single method of propagation in all regions there is need to use different methods at different places depending on the environment. He also emphasized the need for developing dwarfing rootstocks in mango.

Papers presented from Maharashtra, Karnataka, Kerala and Punjab States of India indicated that more than 80 per cent success was achieved when mango plants were multiplied through stone or epicotyl grafting. It was noted that the nurserymen in Maharashtra have already adopted this method for commercial production of the mango grafts. In view of its high percentage of success, it is suggested that the aforesaid practice be adopted in states like Maharashtra. However, further information on age of rootstock, time of grafting and performance be collected before this practice is recommended for wider adoptation in the country.

Significant success has been reported from Andhra Pradesh and Uttar Pradesh for mango propagation through veneer grafting. This practice may be adopted for raising mango grafts in states like Andhra Pradesh and Uttar Pradesh. Whip grafting and soft wood grafting have been found promising for raising mango plants in Madhya Pradesh and under Akola conditions. However, stooling showed significant promise under Pantnagar conditions. In view of the success of various techniques in different states, it is suggested that pilot scale comparative studies may be conducted before definite recommendations could be made for different environments.

The research work reported from IARI, New Delhi indicated promise of multiplication of mango hard wood cuttings through bottom heat. Such studies need to be conducted under different agro-climatic regions of the world and more data is needed to be generated on this subject.

It was emphasized that in propagation studies, cost of raising plants by
