The simple correlation coefficient and path analysis of grain yield and its related components for some genotypes of wheat (Triticum aestivum L.) for two seasons in Iraqi Kurdistan

Shara Jalal Hama, Bestoon Omer, Kazal Rshead

This study was aimed to characterize yield components and plant traits to grain yield. Correlation and path analysis were carried out in same wheat (Triticum aestivum L.) genotypes under field conditions at two winter successive seasons 2012-2013 and 2013-2014 in the fields of Agriculture Research Station at Qlyasan, Faculty of Agricultural Sciences- University of Sulaimani,. In the path coefficient analysis, grain yield represented the dependent ones average spick weight (g) no. of spikes/m2, Spike yield (kg/h), 1000- Grain weight (g), straw yield (kg/h), biological yield (ton/ ha), harvest index and grain yield (ton/ha). The results confirm that the grain yield correlated negatively and high significantly with 1000-grain weight, whereas grain weight / spike correlated positively and high significantly with1000-grain. The character No. of grain / spike correlated positively and significantly with spike length, while grain weight / spike showed significant and positive correlation with spike length. The character 1000- grain weight had significant negative correlation with No. of grain / spike.rnFor the first season, the path analysis showed that, 1000-grain weight gave maximum positive direct effect in Grain yield, while maximum negative direct effect recorded by Grain weight / spike. Highest positive indirect effect exhibited by grain weight / spike and No. of grain / spike both of them via 1000-grain weight, whereas highest negative indirect effect showed by 1000- grain weight via grain weight / spike.rnFor the second season maximum positive direct effect recorded by biological yield in Grain yield, whereas maximum negative direct effect noticed by grain weight / spike. Highest positive indirect effect achieved by grain weight / spike via 1000-grain weight, while maximum negative in direct effect recorded by 1000-grain weight via grain weight / spike.
