CR Dhan 702 (CRHR 102)-2021 SVRC Odisha

Background
India has largest area under rice (about 43.86 mha) and second largest in production (106.0 mt) in the world. Country has so far developed and commercialized over 1300 rice varieties (including 127 hybrids) suitable for cultivation under different rice ecologies. However, meager quantity of quality seed availability (SRR ~40.42%) and high perceptivity to fragie climatic influences, its production is remaining low (3.66 t/ha) as compared to the global averages of 4.53t/ha (FAO, 2016) The situation is even worse in traditional rice growing regions like Odisha (4.17 mha, 1992 kg/ha, SRR-21.65%) and West Bengal (5.38 mha, 2730 kg/ha, SRR-33.67%) where rce is main commodity of livelihood. Most of the cultivable land suitable for rice production has aiready been exploited. The inputs like water and other national resources are being diversfied towards production of other crops as well as in industry and urbanization. The premier rice varieties of green revolution era like jaya and IR-8 have reached to a yield plateau. In this scenario, hybrid rice technology (5-20% more yeld than HYVs) is considered a viable option to increase rice ye’d gobally and meet the future food demand of our ever growing population. Country has 50% nce area suitable (irrigated and favorable shallow-lowland) for hybrid cultivation and seed production, so, this venture has great business scope which is very much fit to the state pan to enhance rice productivity and livelihood.
Technology Details
Hybrid rice found to be more remunerative in yeld (1.0-1.5 t/ha), income (Rs 15000-20000 from cultivation and Rs 75000-85000/ha seed production) and creates additional employment for rural (100-105 additional mandays for per hectare seed production), thus has potential to add extra paddy to natonal food basket and enhance livelihood of deprived farmers CR Dhan 702 (CRHR 102) is a long duration (140-145 days) CGMS based three-lines hybrid released (SVRC-202) for cultivation under irrigated and shallow-lowland area of Odisha. It has long slender grains with average yield capacity of 7.5 to 8.0 t/ha. it can withstand water stagnation (up to 30cm) and iow light conditions Exerts moderate resistant to leaf blast, neck blast and resistant against fase smut; and MR to gal midge. It has high seed producibility (complete flowering synchronization) thus suitable for hybridzing shallow-lowand rice area in the country
