The aromatic IET 21842 (R 1536-136-1-17-1) identified as promising for different states UttarPradesh,West Bengal, Assam and Chhattisgarh. This variety possesses high yield, short bold grain withgood in quality exhibiting superior performance.
• Low genetic variations for grain Fe levels were observed compared to that of grain Zn contents. In screening of homozygous breeding lines, two rice lines viz; R-RF-31 and R 1033-968-2-1 identified from the state and drought breeding trails as High Zinc rice genotypes (> 27 ppm Zn). These genotypes are currently in the pipeline of release of varieties, which will be useful in the drought prone areas of eastern Indian state including CG.
• The eight different genes for gall midge resistance has been identified namely Gm-1(Sarekha), Gm-2 (Sarekha), Gm-3 (RP 2068-18-3), Gm-4 (Abhaya), Gm-5 (RC 5984), Gm-7 (RP 2333-156), Gm-8 (Jhitpiti) and Gm-9 (Line 9). The national identity number allotted is IC 296614.

Crop Protection Entomology
• More than 50,000 rice entries were tested for the Raipur Gall midge and BPH resistance and near about 3000 gall midge and 300 BPH resistant entries were identified as potential donors for various International, National and State level variety development programmes. Insect resistant varieties were developed from Raipur are Asha, Usha, Samridhi, Ruchi, Abhaya Kranti, Bangoli-5, Mahamaya, Bamleswari, Danteswari Samleswari, Chandrahasni, Karmamahsuri etc.
• During the last two decades 20 new Insecticide chemical molecules, two bio and two botanical insecticides were tested and recommended against the major insect pests of rice.
• Based on long term monitoring through light trap catches for different insect pests of rice, major active period of the pest was identified.
Third week of Sept. to last week of Oct is identified as the period of peak activity for most of the pests. In light trap monitoring studies the timings of 6.30 PM to 10.00 PM is identified as ideal time for operating this instrument by receiving maximum adult catches.
