Multiple stepwise regression analysis to estimate the root length, seed yield per plant and number of capsules per plant in sesame (Sesamum indicum L.).

摘要

Ten genotypes of Sesamum (Sesamum indicum L.) were grown in poly vinyl chloride pipes at Gandhi Krishi Vignan Kendra and observations made on shoot and root morphological traits. Multiple stepwise regression analysis technique was used to find the contribution of root and shoot morphological characters on root length, seed yield per plant and number of seeds per capsule. The yield per plant and number of seeds per capsule were obtained at 90 DAS. Regression model was fitted; root length, seed yield per plant and number of capsules per plant was taken as dependent variable and other root and shoot characters are taken as independent variables in the model. The root, shoot length, plant height, capsule length and number of seeds per capsule were made the significant contribution towards seed yield per plant.
