Plant Breeding

As the name of the Institute itself suggests, Plant Breeding Section (under the Crop Improvement Division) forms a major component of this Institute. The contribution made by the scientists of this section is steeped in the history of sugarcane research and development in this country. The novel idea conceived by our founding fathers, viz, Dr. C.A. Barber and Sir. T.S. Venkatraman of using the wild species Saccharum spontaneum as male with S. officinarum as female in sugarcane breeding with the objectives of incorporating gene complexes for biotic and abiotic stresses and for high biomass production resulted in a tremendous level of useful genetic variability. The first successful inter-specific hybrid variety Co 205 was released for cultivation from this exercise way back in 1918. This paved the way in revolutionizing sugarcane agriculture and sugar industry not only in India, but also in most of the sugarcane growing countries of the world. This landmark achievement is unparalleled in the annals of crop breeding history. Most, if not all, of the present day varieties world-over have the Coimbatore bred canes in their genealogy. A number of varieties evolved at this Institute has sustained the sugar industry in the country for nearly a century and made India self sufficient in sugar production.

The sugarcane breeding work in the main campus is facilitated by the National Hybridization Garden (NHG), where scientists and breeders from all AICRP centres assemble and make crosses after selecting proven parents. An innovative mechanism in the form of elevated runways in NHG has greatly facilitated making crosses easier even for female scientists. To augment the work at NHG, the hybridization programme is also carried out at the farm located at Agali Research Centre. The seed is later collected, dried and the defuzzed seeds are dispatched to the coordinating centres across the country.

The major part of seedling and clonal evaluation and selection is carried out at the breeding section located at East Chittirai Chavady (ECC) about 3 km from the main Institute. Clones suitable for North India are tested at the Regional Centre, Karnal. The best performing clones are assigned Co- numbers (‘Co’ indicating Coimbatore selections) and pushed to the next level of zonal trials.

Sugarcane Varieties

Historial Landmark

Development of varieties is the central area of research since the inception of the institute in 1912. It was the first of its kind to start work on breeding varieties for sub-tropical conditions. The first commercially successful inter-specific hybrid in the world, Co 205, a hybrid between cultivated sugarcane, Saccharum officinarum and the wild grass S. spontaneum became popular in Punjab province during 1920s. Varieties such as Co 213, Co 214, Co 281, Co 285, Co 290, Co 312, etc., bred by this institute revamped sugar industry in India. From 1926, the Institute started developing varieties for tropical India as well.

The varieties developed later by this Institute such as Co 419, Co 453, Co 740, Co 997, Co 1148, Co 62175, Co 6304 and Co 6806 are some of the very successful varieties spread across the country. The variety Co 86032 notified for release in the year 2000 occupies most of the sugarcane area in tropical India at present. Recently released sub-tropical varieties such as Co 0118 and Co 0238 are gaining popularity among the farmers of Haryana, Punjab, Western UP, Uttarakhand and Bihar. Thus varieties evolved by the Institute have elevated the status of the nation from a sugar importer to the largest manufacturer of sugar in the world today. The varieties evolved at this Institute are being grown all over India and is being used as breeding stocks in 26 other countries in the world as well

Activities Under AICRP

ICAR – Sugarcane Breeding Institute, Coimbatore was established in the year 1912 and served for more than 107 years in evolving superior varieties of sugarcane to cater the needs of the various agro climatic zones in the country. The Institute is located at Coimbatore (77°E longitude and 11°N latitude) in Southern India on the leeward side of Western Ghats at 427 metres above mean sea level and receives an annual average rainfall of 650 mm, mostly during the months of October-December. The maximum and minimum temperatures range from 35.2°C to 21.7°C respectively. During the last century, the institute had contributed to the varietal diversity of the nation, as it was evident from the fact that more than 90% of the area under sugarcane in the country is covered by varieties which were bred or derived from crosses made at Coimbatore. In tropical region, 60% and 38% of the sugarcane area is under varieties developed by ICAR-SBI and other sugarcane breeding centres in collaboration with ICAR-SBI respectively. In subtropical region also, varieties developed by ICAR-SBI and other sugarcane breeding centres in collaboration with ICAR-SBI are occupying 75% and 23% of the sugarcane areas respectively. During 2018-19, Coimbatore canes (Co canes) covered 70.06 % of the area under sugarcane in the country. In addition, the varieties bred at Coimbatore are also cultivated/ used as parents in 28 other countries in the world. The National Hybridization Garden functioning at ICAR-SBI, Coimbatore is the basis for creating genetic variability for the whole nation as it facilitates and coordinates the crossing programme of 24 sugarcane breeding centres distributed across five agro-climatic zones of the country. The National Distant Hybridization Facility created at ICAR-SBI, Research Centre at Agali is open to all the AICRP(S) participating centres to make wide crosses involving different genera of Saccharum complex for strengthening the pre breeding activities.
