Plenary Session 1: RICE HISTORY AND DEVELOPMENT
Chairman : Dr. EA. Siddiq
Co-Chairman : Dr. M. Rangaswamy
Rapporteurs : Dr. D. Sudhakar and Dr. A. John Joel
Lecture 1 : "Memoirs and Milestones of Paddy Breeding Station" by
Dr. S.R. Sree Rangasamy
Dr. S.R. Sree Rangasamy narrated the evolution of Paddy Breeding Station (PBS) which was established in 1912 and high lighted the pioneering research efforts of Doyens of rice Science, Mr. F.R. Parnell, Mr.R.O.Iliffe and Dr. K. Ramaiah. He also narrated the pioneering work done in PBS highlighting evolution of the different breeding strategies adopted in developing series of improved CO varieties of rice especially of the pureline selection. GEB24, the first release which proved to be an excellent base for evolution of many rice varieties. The first ever drought tolerant variety CO 31 developed from inter specific crosses with the wild rice O. perennnis; blast resistant varieties CO4 and CO25; relatively more fertilizer responsive CO23 and the first hybrid rice CORH1 were other important milestones. He also presented the land mark genetic discovery research of PBS highlighting publication of first gene symbol, first linkage group, O. pernennis as the progenitor of the Asian cultivars and secondary polyploidy nature of rice. Living up to its traditions, the house was gratified of its continued endeavour of PBS to improve progressively rice by integrated breeding approaches involving traditional and molecular breeding strategies for the food security and prosperity of mankind.
Lecture 2 : "Evolution of rice in Tamil Nadu - An ancient history" by
Mr. M. Murugan
Mr. Murugan, in his lecture, brought out through literary and historical and archeological evidences on how ancient Tamils were familiar with agriculture in general and rice in particular. His excellent presentation traced how Tamil language, Tamil civilization, Agriculture and Rice Culture were interlinked since over 3000 years ago. This work of this kind should be pursued and findings be published in reputed international journals.
Lecture 3 : "All India Coordinated Rice Improvement Project: Role of AICRIP in
Rice Improvement -History and Development" by Dr. B.C. Viraktamath
Dr. B.C. Viraktmath narrated comprehensively how the All India Coordinated Rice Improvement Programme (AICRIP), an experiment in applied research and collective wisdom in planning, generating knowledge and genetic material and Multi Location Evaluation of breeding lines has enabled the country to evolve close to 1000 varieties and hybrids for different rice ecologies and socio-economic demand. The coordinated project, taking advantage of a large number of cooperating centres and hotspot locations, should evaluate the entire germplasm for traits of economic significance. The programme, jointly with CRRI and select SAUs such as TNAU, should genetically characterize the germplasm for the breeders to make use of non-allelic gene sources for breeding future varieties for tolerance/resistance to biotic and abiotic stresses by gene pyramiding with the use of marker assisted selection.
Lecture 4 : "Landmarks in Rice research globally and in Indian Context" by
Dr. B.N. Singh's narration on development of rice breeding research brought out some valuable information to the knowledge of rice breeders. It specifically identified dwarfing gene sources alternative to the widely used DGWG in Pankaj (IR5) and CR1009 through the induced dwarf mutants of Jangannath. He also emphasized that the future rice improvement programmes should focus on breeding for resistance to biotic and abiotic stresses, input use efficiency especially fertilizer, nutrients, water and towards sustainable rice production.
Lecture 5 : "History, Development, Science and Scope of SRI" by
Dr. Norman Uphoff, USA
Dr. Norman Uphoff's presentation drew attention to the advantages of System of Rice Intensification (SRI) method of rice cultivation in closing the yield gap and increasing, thereby production and productivity. Recognizing its limitations as widely adaptable technology across major rice growing ecologies, he emphasized the scope for continuously improving this technology for enhanced benefits.
Lecture 6 : "Bio diversity of wild rices (Oryza sp)" by Dr.M.Subramanian
