  • One of the eminent scholars of our time, Padma Shri Prof. Siddiq writes for RKMP on "Rice Research in India" covering various aspects. This comprehensive paper covers different facets of rice research carried out in India since Independence. While going through this paper, we hope that you will experience the transformation that the country has seen in last five decades.
  • Welcome to the journey of Indian rice research!

  • Development of productive package of cultivation practices

    Crop Production:

    Aside developing packages of practices appropriate to high yielding varieties released for different rice ecologies, crop production group comprising agronomists, soil scientists and microbiologists has been engaged in various production optimization related research. It included broadly study of use efficiency of water, fertilizer etc., soil fertility management,...

  • Conservation of genetic resources

             Rapid erosion of genetic variability, which forms the bedrock of progressive crop improvement, is of great concern today. Among the research priorities in rice, collection conservation and evaluation of genetic diversity have been receiving due attention ever since the founding of the Central Rice Research Institute at Cuttack (Orissa) in 1946. It started with the exploratory survey of genetic...

  • Production and supply of quality seed

                   In heralding the Green Revolution, role of quality seed had been as crucial as the high yielding varieties. In the absence of a system for organized production and supply of quality seed, especially when the country had gone for rapid and extensive adoption of high yielding varieties, the high yield technology would not have made the kind of impact it has made. Realizing that...

  • Development of germplasm with new yield thresholds

                    In the fourth decade that placed emphasis on further raising the genetic yield level of irrigated rice, possibilities of replicating China’s success story of hybrid rice technology and prospects of developing new plant type varieties were explored. As dealt elsewhere, hybrid breeding research was launched in network mode involving 10 major rice research...

  • Breeding for adaptation to rainfed Ecologies

            Excessive and continued research attention given but inevitable for sustaining the high productivity level of irrigated rice, as many perceive, has been at the expense of equally large and potential rainfed ecology. Accounting for over 55% of the rice area, the ecology characterized by varied water regimes viz rainfed shallow lowland, (14 million ha) rainfed upland (4 million ha) and deepwater (1...

  • Varieties resistant to biotic stresses

                At the time of the introduction of the exotic high yielding varieties, pest problem was not as serious as it assumed subsequent to their advent. As against three insect pests viz stem borer, gallmidge and earbug and two diseases viz blast and brownspot affecting rice, today the number has increased to 13 diseases and as many insect pests and their presence in varied pathotype/biotype forms with higher...

  • Rice Improvement during post IR-8 Period

            Rice improvement research in India during the post IR8-Jaya period may be broadly discussed under five phases namely (a) the first decade of varietal breeding for different crop seasons and grain quality (b) the second decade of aggressive breeding for insulation of varieties with resistance against pests (c) the third decade of shift in breeding emphasis for adaptation to rainfed ecologies (d) the...

  • The era of food deficiency and early initiatives for accelerated advance of rice production

          Rice research in India is one hundred year old. Aiming at enhanced productivity and stability against stresses, early research efforts had been confined to introduction of exotic varieties, evolution of varieties through pureline selection in landraces well adapted to various growing environments and crossbreeding mainly for improvement of grain quality and...

  • Introduction

    India is the home to rice, being on the periphery of the Centre of origin, domestication and subspecific differentiation of the Asian cultivar species Oryza sativa and remaining the worlds’ largest rice growing and second largest rice producing and consuming country. Housing all the diverse rice ecologies it is one of the richests in rice genetic diversity. Paradoxically, it remained for long the home for the largest number of under-nourished. The...
