I think we are getting there gradually! and this should interest government and donor agency in different countries to assist in continuous research on the subject, training programmes and dissemination of the new innovation to yam farmers for adoption.

Depending on the day-length and age of mother plants, the vine cutting will just form roots and microtubers. Aged plants (those plants in the reproductive phase where rapid tuberization and flowering occur) will produce vine cuttings with only roots and tubers, while non-aged plants (plants in vegetative phase where elongating stems and leaves occur before rapid tuberizaion and flowering) under long day-length would produce vine cuttings with roots, shoots, and tubers. Tuberization will be enhanced by short day-length while the growth of the top (stem and leaves) will be hampered by short day-length. Long day-length has the opposite effect. For this reason, the best season for vine propagation is under long day-length. However, if you harvested small tubers from non-shooted vine cuttings, those small tubers will produce seed-tuber in the next cropping season. They can then be used for vine propagation again after the dormancy is broken. Ideal planting materials and season for non-aged plants: 3 months after sprouting with new lateral branches and under long day-length, which promote shooting from vine cuttings. Best regards, Kikuno Dear Zachary,

They are already 5 months old!! I have tried this method in Kenya but the vine cuttings do not seem to sprout..what could be the problem? They are already 5 months old!!

This is a welcome development especially as there will be a drastic reduction in the use of table yam as propagule. Here comes the best technology for seed yam production.

How Do I get started? Interested in detailed procedures of the tuberless yam propagation. Sincerely.

Kindly extend collaboratory research work to interested researchers. In my Institution, tuberless yam through the use of botanical seed of D. alata was produced last year. It was a fantastic experience. Thanks The technology will reduce cost incurred in procuring planting materials in yam. Kindly extend collaboratory research work to interested researchers.

Sun, 14 Mar 2010 16:18:35 +0000 http://r4dreview.org/?p=619#comment-2577 Dear Sir, This is an innovative idea. However, I wish you include yam scientists and researchers from neighbouring Universities to popularise the technology among the yam growers. I am a staff of LADOKE AKINTOLA UNIVERSITY OF TECHNOLOGY, OGBOMOSO. I had a similar collaboratory trials with Dr Asiedu and Mr Okonkwo last year using seed to produce yam seedlings, plantlets and seed yams. The results is fantastic. I wish to carry out further studies on tuberless yam through your institution. Kindly direct further. Thanks Dear Sir,
