Abstract:
The genetic analysis for crop improvement programme is a prerequisite for the breeding programme. The purpose of this study was to determine the extent and direction of association between yield and yield attributes. An analysis of yield determinants in 50 wheat genotypes under randomized block design was conducted twice at the Powarkheda Research Farm, Zonal Agriculture Research Station, Narmadapuram, Madhya Pradesh during Rabi 2019-20 and 2020-21. Studying the association between yield and yield-contributing characteristics at the phenotypic level revealed that grain yield/plot was positively and significantly associated with biological yield, harvest index, and test weight. Path co-efficient and regression analysis revealed that biological yield, harvest index, flag leaf area, number of grains/spike, days to heading and number of tillers/plant proved to be the major direct components of yield.
