Correlation, path analysis, heritability and genetic advance for morpho-physiological character on bread wheat (Triticum aestivum L.)

Author(s): Rahul Singh Rajput
Abstract: The present investigation entitled “Correlation, path analysis, heritability and genetic advance for morpho-physiological characters in bread wheat (Triticum aestivum L.)” was undertaken to study the Correlation, path analysis, heritability and genetic advance for grain yield and its components in F1 generation of wheat through Line X Tester analysis. Experiment was conducted with 2 replications and 54 genotypes consisting 10 lines viz., 33rd ESWYT150, 20th HRWYT213, 20th HRWYT235, 45th IBWSN1021, 14th FHBSN6418, 36th SAWSN3065, PBW658, KB2013-03, KB2013, VW921 and 4 testers viz., GW273, GW366, RVW 4106, SUJATA and their 40 crosses made in L X T mating fashion in randomized block design at experimental Research Farm, College of Agriculture, Gwalior, (M.P.) during 2014-2015. Genetic analysis revealed that Canopy temperature index and harvest index recorded high value of heritability and genetic advance. Genotypic path analysis revealed that test weight and weight of grain/spike exhibited positive and strong association with grain yield and highest positive direct effects on grain yield. The selection for yield contributing test weight and weight of grain/spike must be given preference along with grain yield for speedy improvement grain yield.
