Current Status of Hybrid Rice

  
 

Development of high yielding hybrids is one of the major objectives of the project. During the last 10 years more than 1000 experimental hybrids developed by different network centers, IRRI and private sector seed companies have been evaluated in multi-location trials. Of these, 13 public bred hybrids showing consistent yield superiority over local inbred check varieties have been released for commercial cultivation in different regions by the respective state variety release committees (Table - 1).

Besides, three private bred hybrids viz., PHB-71 (POC) , HRI-120 and PA-6201 (HRI) have been released by Central Variety Release Committee (CVRC) and another 6-8 hybrids are being marketed by private seed companies. All these hybrids possess a mean grain yield of 6-8 t/ha with 15-20% yield superiority over corresponding high yielding inbred check varieties.

@OFT=On-farm trials * Private bred hybrid released by CVRC

Out of the 16 hybrids released so far, large scale seed production of five hybrids viz., DRRH-1, KRH-2, Sahyadri, PHB-71 and PA 6201 has been taken up by the public and private sector seed agencies. Hence, seed of above mentioned hybrids is available to the rice farmers for undertaking large scale cultivation.

At present hybrid rice is reported to be grown approximately 200,000 hectares. Area under hybrid rice will further increase after heterotic hybrids suitable for high productivity areas of Punjab, Haryana, Coastal region of Andhra Pradesh and Shallow lowland areas are identified and an effective transfer of technology programme is taken up vigorously in the target states.
