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 F
1 generation of wheat through Line X Tester analysis. Experiment was conducted with 2 replications and 54 genotypes consisting 10 lines
viz., 33
rd ESWYT150, 20
th HRWYT213, 20
th HRWYT235, 45
th IBWSN1021, 14
th FHBSN6418, 36
th 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.
