Wheat- Diversity – Variation- Agronomic – Cluster analysis


Two field experiments were carried out during the two winter seasons of 2011/12 and 2012/13 at the Farm of Research and Production Station, National Research Centre, Al Emam Malek Village, Nubaria District, Al Behaira Governorate, Egypt. The investigation was carried out with 8 bread wheat genotypes to assess the variability of the genotypes or the genetic diversity based on agronomic parameters using cluster analysis. The results revealed that the genotypes significantly differed from each other in the studied characters. Regarding the, number of days to 50% heading cultivars Gemmeiza 10 and 7 recorded the highest values, respectively; however, the cultivar Giza 168 recorded the lowest one. The cultivar Sids 12 recorded the highest number of spikelets/spike, number of grain/spike and grain weight/spike; however, the cultivars Sakha 94, Gemmeiza 9, Giza 168 and Gemmeiza 10 recorded the lowest values, respectively. Cultivar Sids 12 recorded the highest spikes number/m2; while, Sids 1 recorded the lowest value on the other hand, cultivar Sids 1 recorded the highest seed index, while Sids 12 recorded the lowest value. The cultivar Sids 12 recorded the highest value of grain yield/ha, however, the cultivar Sids 1 recorded the lowest value. Due to Cluster analysis: the 7 studied characters were used to construct a similarity matrix using the Jaccard coefficient and used to generate, phenogram showing similarity among all the variety.
