Genetic parameters and their association with grain yield in quinoa (Chenopodium quinoa Willd) under late sown condition

One hundred forty promising lines of quinoa were evaluated during rabi season of 2019–2020 to study the genetic parameters and their association with grain yield and its attributes. Heritability was high for all the traits. High heritability coupled with high genetic advance expressed as percentage of mean was observed for grain yield per plant, number of primary branches per plant, days to maturity, plant height and number of inflorescence per plant. Moreover grain yield per plant exhibited positive and significant association with plant height, length of inflorescence per plant, number of inflorescence per plant, number of primary branches per plant and stem diameter per plant. Therefore selection based on these characters would be effective for improving the grain yield and its attributes in quinoa under late sown condition of Chhattisgarh state.
