Abstract:
Current research was conducted with objective to study association of cause and effect relationship of yield contributing characters on yield under limited irrigation condition. This study involves forty three genotypes of wheat evaluated at Agriculture Research Station, Niphad during Rabi 2018-19 in a Randomized Block Design with two replications. Correlation study revealed that, grain yield showed strong significant and positive correlation with productive tillers per meter, 1000 grains weight, peduncle length, number of flower per spike, flag leaf length, number of grains per spike and number of spikelets per spike. While spike length, coleoptile length and plant height showing non-significant positive correlation with grain yield. Grain yield showed significant negative correlation with days to maturity and days to 50% heading. In the present study, the correlation analysis revealed the association pattern of different yield components with grain yield represents the correlation coefficient between the characters with seed yield at both genotypic and phenotypic levels. In the present study, Path coefficient analysis was carried out at genotypic level taking grain yield as dependent character and all the characters which exhibited significant association with grain yield were considered as independent characters. Positive direct effect of seed weight on yield per plant was noticed and this was supplemented by positive indirect effects through stem girth, length of inflorescence.
