NEW DELHI : In a significant move, scientists of NRC on Rapeseed-Mustard, Bharatpur successfully developed a hybrid of Indian mustard through heterosis breeding using moricandia cytoplasmic genetic male sterility system.

The new breed named NRC Sankar sarson (NRCHB 506) is the first mori candia CMS based hybrid of Indian mustard in India and important milestone in Brassica research programme of the country.

The developed hybrid was identified for release primarily for Rajasthan and U.P. states.

Dr. K. H. Singh, Senior Scientist and key breeder of this NRC Sankar sarson hybrid, reported that the hybrid had shown superiority for oil yield by a margin of about 26, and 20 per cent over existing popular varieties of the region viz., Maya and Varuna, respectively in 11trials across 5 states.

The yield recorded in yield evaluation trials was up to 32 q /ha at some of the location. This hybrid is of medium maturity duration of 133 days, medium tall 190 cm and has 40.6 per cent high oil content. It has shown wide adaptability.

Rapeseed-Mustard is an important oilseed crop commodity contributing 26.1 and 29.1% respectively to the total oilseed hectarage and production in India. During 2005-06 the productivity of rapeseed-mustard was about 2.3 times i.e. from 483 kg/ha to 1117 kg/ha, as compared to that of 1967-68 with five fold increase in production.

There has been a remarkable increase in rapeseed-mustard production and productivity during the last two decades. The area and production under rapeseed-mustard was 6.33 mha and 6.69 mt during 2006-07 with a productivity of 1057 kg/ha.
