Genetic variability, heritability and genetic advance for yield and yield components in pea (Pisum sativum L.)


Author(s): Jayashri Barcchiya, AK Naidu, AK Mehta and Anubha Upadhyay

Abstract: Twelve pea genotypes 7 lines and 5 testers crossed in a Line x Tester mating design were evaluated with their 35 F1's along with parents in a randomized block design in three replications at Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) during rabi season of 2015-16 and 2016-17. The variability, heritability and genetic advance as percent mean were studied for all the characters under investigation. The estimates of heritability varied from 32.3 % (harvest index) to 99 % (plant height). The heritability estimates were moderate for harvest index. For remaining characters, estimates of heritability were high. Genetic advance as percent mean was highest for weight of hundred seed, days to 50 % flowering, green pod yield per plant, number of pods per plant, seed yield per plant, days to maturity and shelling percent while characters viz. protein content in seed, no. of seeds per pod, biological yield per plant, pod length, no. of effective nodes per plant no. of branches per plant, showed moderate genetic advance, while harvest index showed lowest genetic advance. The consequences of heritability coupled with high genetic advance showed for characters viz. days to 50 % flowering, days to maturity, plant height at maturity, no. of pods per plant, green pod yield per plant, shelling %, weight of hundred seed, seed yield per plant thus, these characters may be improved through selection method.
