Highlights of 41st Annual Rice Group Meeting

41st Annual Rice Group Meetings

The 41st All India Rice Research Group Meeting was organized by Directorate. of Rice Research at ANGRAU, Hyderabad during 14-17 April, 2006. Dr. N.G.P. Rao Former Chairman, ASRB inaugurated the session under the Chairmanship of Dr. G. Kalloo, Deputy Director General (Crop Science & Horticulture). More than 400 delegates comprising the cooperators of various Centres, Directors of Research of SAUs, Representatives from Private Sectors, Non Government Organisations, Media persons, Process Industries participated in the meeting. Some of the highlights of the above workshop are as under:-

2. IET 18181 (JKRH 2000) Identified for West Bengal, Orissa & Bihar Resistance to Leaf Blast, Brown Spot, Sheath Blight, Sheath Rot and RTD - average mean yield: 6222 kg/ha.

ii) Varieties:

Sl.No. Name of the variety Growing areas Remarks
3. IET 17901 (RR 347-2) direct seeded rainfed upland conditions of Gujarat & Orissa Resistance to leaf Blast, Brown Spot and Sheath Rot combining good grain quality features- average mean yield : 1833 kg/ha.
4. IET 17868 (CR 314-10) RR 272-8-29 Identified for irrigated eco-system mid early duration for U.P, Bihar, Jharkhand and Assam Resistance to Gall Midge Biotype-1 and Leaf Blast; MR to Brown Spot and Sheath Rot; with short bold grains with acceptable grain quality features - average mean yield: 5226 kg/ha.
5. IET 17920 (SPRLR 79234-51-2 Identified for irrigated eco-system for medium duration Andhra Pradesh, Tamil Nadu, Kerala & Karnataka, Bihar, W.B., Chhattisgarh Resistance to Leaf Blast and Neck Blast average mean  yield: 6141 kg/ha.
6. IET 17276 (CRM 2007-1) Identified for Basmati growing areas of Punjab and Haryana. Comparable to Taroari Basmati possessing resistance to Leaf Blast, Neck Blast and Brown Spot - average meanyield  3793 kg/ha
7. 16863(VL Dhan 86(VL 97-3861) Identified for irrigated hill areas of Uttaranchal and Himachal Pradesh. including qualifying checks, the proposed culture of 98 days flowering - average mean yield  4926 kg/ha

B. Production Technology:

  • The trials on rainfed uplands revealed that line sowing with optimum seed rate @ 60 kg/ha + application of FYM (15 days before sowing) alongwith nitrogen in 3 splits (50% at 15 days after sowing + 25% P1) of respective locations is the most promising in enhancing rice yields.
  • New herbicide molecules recommended for transplanted rice are triasulfuron (20 WSG) + pretilachlor (50 EC) @ 0.006+ 0.500 kg a.i./ha
  • Bensulfuron-methyl @ 0.05 kg a.i./ha
  • And triasulfuron. 009 kg a.1/ha at 5-7 DAT

C. Plant Protection Technology:

  • Indoxacarb, a new insecticide belonging to oxadiazine group @ 30 g a.i./ha was effective against stem borer and leaf folder.
  • Integration of stem borer tolerant variety "Vikas" and pheromone mediated mass trapping was the best strategy in YSB endemic locations (Andhra Pradesh) while, timely insecticide application of safer insecticides like cartap hydrochloride and imidacloprid was the best option in BPH endemic location (Andhra Pradesh Maruteru).
  • The entry, IET No. 18353 (OR 1885-16-34, IR 72/ Kanchan) which was found to possess low susceptibility index and a high promising index for leaf blast, and resistance to neck blast and sheath blight, can be used in the crop improvement programme.
  • Propiconazole (Tilt 25 EC) along and its combination with diefenconazole (Armure 30 EC) which were found best in reducing the glume discoloration and improving the grain yield, can be recommended for use in the rice growing areas affected with glume discoloration

D. Breeder Seed produced:

  • An Indent of 1649.68 q/ was received against which a total of 2849.79 q/ of breeder seed of different varieties and parental lines of hybrids were produced.
