PATH COEFFICIENT ANALYSIS OF YIELD AND YIELD COMPONENTS IN BREAD WHEAT (TRITICUM AESTIVUM L.) GENOTYPES MEHMET AYCICEK AND TELAT YILDIRIM*
Abstract: With the trials conducted across two locations and over two years,
the correlation coefficients and path analysis were calculated between
grain yield and yield components of 20 bread wheat genotypes. Positive
and significant correlation was found between yield and plant density,
plant height, grain number per spike, grain weight per spike and 1000
kernels weight. Grain yield was negatively and significantly correlated
with time to heading. Positive direct effect of plant height and grain
weight spike-1 and negative direct effect of time to heading associated
with significant correlation with grain yield suggested that these yield
components may be a good selection criteria to improve yield of wheat
genotypes. Programme of Field Crops, Bingöl Trade College, Firat University, Bingöl, Turkey. Eastern Anatolia Agriculture Research Institute. |
