Charcterization of agronomic traits and grain quality of some wheat landraces

Abstract EN

This study was carried out at Nubaria Research Station Farm to evaluate of 12 wheat land races genotypes during two seasons 2014/15 and 2015/16.

Analysis of variance was computed to measure genotypic and phenotypic coefficients of variation and broad sense heritability (h2) for yield and its components.

Also, Chemical compositions of whole meal wheat genotypes were determined.

Results indicated significant differences among wheat genotypes for all studied traits except spike length (cm) in the combined data.

Results indicated that high values of genotypic (GCV) and phenotypic (PCV) coefficients of variation were obtained by grain yield (67.84 and 68.83), followed by number of spike/m2 (35.54 and 38.57), number of kernel/ spike (34.02 and 36.33) and 1000-kernel weight (26.50 and 29.35) respectively.

High heritability coupled with high genetic advance was observed for most traits.

Whole meal wheat genotype L1 contain the highest content of crud protein and ash which were (13.23 and 2.01 %) respectively.

On the contrary, L1 had the lowest content (82.78 %) of carbohydrates.

In addition to, the L10 had the highest crud fat content compared with the other wheat genotypes.
