ABSTRACT
Correlation and path analysis for seed morphometric as well as yield-related traits were performed
on five bread wheat varieties, each sown on an area of one acre; this investigation was carried out to
check the influence of these traits on the grain yield of bread wheat (Triticum aestivum L.). Digital
image analysis (DIA) is a quantitative technique to phenotype seed morphometric characteristics with
high accuracy. Multivariate analysis was performed to determine the relationship bdeetween ground
cover (GC) and seed size and grain yield (GY). Significantly important traits were identified by principal
component analysis (PCA). Applying the multiple linear regression model, grain yield was predicted
with the help of ground cover and seed shape traits. The association of the studied traits was quantified
with a structural equation model. The impact of spikes per meter square (SPMS) and thousand kernel
weights (TKW) on grain yield was significant (p-value <.01). Plant height has a detrimental impact
on grain yield, and the grain yield was influenced by two features: spikes per meter square (SPMS)
and grain weight per spike (GWS), which have a direct impact on thousand kernel weight (TKW).
The present research aims to feature the relationship between yield-contributing characteristics and the digital ground cover of the wheat crop. The present work uncovered the fact that digital ground
cover (DGC) influences the seed length, area, and perimeter.
