Abstract
The relationships between agronomic traits and grain yield were investigated in 30 genotypes of bread wheat. These genotypes raised in a randomised complete block design (RBD) with three replications during rabi season of 2016-17 at the Research Farm of Dept. of Genetics and Plant Breeding C.C.S. University Campus, Meerut (U.P.) India, using normal field management practices (i.e., 200 kg/ha fertilizer; N:P:K = 8:8:8). The data were recorded on 10 characters; days to heading (DTH), days to 50% flowering (DTA), days to maturity (DTM), plant height (PH), tiller number per plant (TNPP), number of spikelets per spike (NSPS), spike length (SL), grain number per spike (GNPS), 1000 grain weight (TGW) and grain yield per plant (GYPP). Statistical analyses were conducted for diversity; ANOVA, heritability (h2), genetic advance (GA), coefficient of variation (CV), correlation, path analysis, genetic divergence etc. The result of ANOVA was significant almost all the traits between the treatments, similarly, the range of CV was from 0.34 (TGW) to 7.77 % (GYPP), the range of PCV and GCV were from 3.08 (DTM) to 45.02 (GYPP) and 2.98 (DTM) to 44.34 % (GYPP) respectively. The very high heritability was detected all the traits with the range from 93.75 (TNPP) to 99.95 % (TGW), the genetic advance (GA) was found with range from 2.62 (SL) to 18.19 (GYPP). Likewise, maximum positive correlation (0.92) was found between the DTH and DTA and the result of path analysis indicated, the tiller no showed maximum positive direct effect (0.56) on grain yield, while direct and negative effect of grain yield with DTA.
