Abstract: A staple food for most Asians, rice is a cultivated plant in the Poaceae family. Genetic modification and rice farming have generated a lot of research and development work, especially in the areas of production and grain quality. A major contributing reason to the rising cost and duration of rice harvesting, lodging frequently results in a notable reduction in output. One strategy is to identify a novel plant species possessing the perfect shape, big panicles, high photosynthetic efficiency, and resistance to lodging. The study was conducted at the Department of Genetics and Plant Breeding, Research Cum Instructional Farm, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, India. 32 rice genotypes, including four checks (IR-64, Indira aerobic-1, Pusa 1121, and Dubraj selection-1) were included in the experimental materials.

In light of this, the current study found a correlation between yield and lodging resistance that may be exploited in subsequent crop enhancement initiatives.
