Abstract

Seven wheat genotypes (Triticum dicoccum) and the local check sham5 variety were planted during growing season 2010/2011under rainfed conditions using RCBD with three replications. Yield components (number of total and fertile tillers, number and weight of grains per spike, weight of thousand grain and individual plant grain yield) were studied in two sites in order to define the differences between the studied genotypes in both sites and to provide the superior genotypes for breeding programs. Results showed that the genotype PW70 was significantly superior in (grain yield, number and weight of grain per spike) comparing to check. While, the genotypes (PW96, PW119, PW123) were significantly superior in thousand grain weight comparing to check, as well as the genotype (PW81, PW127) were significantly superior in total and fertile tillers number comparing to check. Most traits were significantly superior in Al-Ghab site.

Highlights

Wheat is one of the most widely cultivated cereal crops throughout the world [1], used for human consumption and to feed animals [2], and it considered as the main crop in Mediterranean Region [3]
Results showed that the genotypes (PW81, PW127) were significantly superior comparing to control sham5 in number of total tillers which was (12.17, 10.83, and 8.33) respectively for each of them as a result of the genetic variation between them
There were no significant differences between two sites in number of total tillers

Summary

Introduction

Wheat is one of the most widely cultivated cereal crops throughout the world [1], used for human consumption and to feed animals [2], and it considered as the main crop in Mediterranean Region [3]. Primitive wheat is the earliest cultivated form of wheat in which many researches insists on the importance of primitive species of wheat as a key to enhance the commercial varieties, so we need to evaluate variance in different genotypes of wheat especially for tillers and grain number and thousand grain weight [7]. Grain yield is a complex trait affected by other yield traits such as fertile tiller number and grain number per spike and thousand grain weight [10,11,12,13] evaluated 41 genotypes of wheat and their results showed significant differences in yield traits such as number of tillers per plant, grain number and thousand grain weight. Evaluated twelve genotypes of wheat and found significant differences in thousand grain weight and number of fertile tiller and grain yield
