Phonotype and Genotype variation and correlation , Path analysis to yield and yield components to varieties of wheat Triticum aestivum L.


An Experiments was conducted Latifyia station research through 2003 – 2004 . Twelve verity of wheat was uses to study the variation in growth and yield , yield component and percentage of heredity , Relationship between correlation and same characteristic study and path analysis coefficient between yield and components .Randomized Complete Block Design (R.C.B.D) was used . The data showed the variety of wheat difference significantly to height plan , number of spead / m2 , number of seed in panicle , tall of speake and weight of 1000 seed and yield of grain , percentage of Heridity was ( 198.31 – 78.6 ) % . These is simple correlation between yield and grain yield , harvest index and number of pankle / ml . pathc analysis coefficient use to study effects of correlation . The harvest index it use to indicter to select to improve the wheat varieties
