Lodging in winter wheat may cause serious losses in productivity, grain quality and harvest efficiency. To understand the lodging pattern with respect to morpho-physiological parameters, a field experiment was conducted at Research Farm, Indian Agricultural Research Institute, New Delhi, India during rabi season with 24 wheat genotypes and laid out in randomized block design (RBD) with three replications. Results indicated that morpho-physiological parameters, viz., the stem strength of lodging tolerant genotypes was significantly higher due to thicker stem and lower second internodal length compared to susceptible genotypes. Further, the stem strength was directly proportional to the lodging resistant factor index (LRFI). Yield and yield attributes were directly proportional to the Stem strength and LRFI as higher stem strength contributed significantly towards holding up of strong sink potential. Principal component analysis revealed that C 306 indicated greater second internodal length (SIL), leaf area (LA), plant height (PH) and lower LRFI, chain weight (CW), harvest index (HI), grain yield (GY) and grain weight per ear (GWPE). GW 143 showed higher GY, HI and GWPE. HD 2934 indicated higher G No, while Raj showed the least. CW was recorded with better in Dl 788-2.
