The biannual experiment was undertaken in SGCARS, Jagdalpur, Indira Gandhi Krishi Vishwavidyala, Raipur, CG, India, during Kharif 2012-13 and 2013-14 to validate the significance and validity of local check variety to screen medium duration rice genotypes. Beginning from National check (IR 64), six entries recorded at par results namely CR-2706 (4875kg/ha), CN 1446-5-8-17-1-MLD 4 (4917 kg/ha), NP-124-8 (5722 kg/ha), CR-2641-26-1-2-2 (5750 kg/ha), NK 6303 (4967 kg/ha) and KPH 371 (5656 kg/ha) including the local check (5431 kg/ha) in Kharif 2012-13. We can interpret that approximate 35 percent genotypes were allowed to proceed. In subsequent experiment i.e. Kharif 2013-14, the four checks namely hybrid check (US 312); National Check (IR-64); Regional check (Lalat) and local check (Chandrahasini) found to be good standard to identify test entries with 4231, 3821, 4564 and 4154 kg/ha yield respectively. Lalat, the regional check (Eastern), had higher yield and phenotypic acceptability and only five entries (UPRI 2012-18, MTU 1056, RH 664, BPH 115, and CN 1752-18-1-9-MLD 19) could go beyond. Similarly, HKR 08-62 (4467 kg/ha), US 312 (4231 kg/ha),  UPRI 2012-18 (4615 kg/ha), OR 1929-4 (4744 kg/ha), MTU 1056 (4718 kg/ha), Lalat (4564 kg/ha),RH 664 ( 5000 kg/ha), BPH 115 (4756 kg/ha), CN 1752-18-1-9-MLD 19 (5833 kg/ha) and HKR 08-83 (4487 kg/ha) found to be superior to local check. National check (IR 64) and regional checks (Lalat) were found suitable; however since many new comparative varieties have been released so far, further review necessitated. Regarding local check, Chandrahasini is quite phenotypically acceptable option to screen mid-early duration rice varieties for Southern Chhattisgarh region.
