The main factors and genetic rules of wheat yield traits were studied through the investigation of 9 agronomic traits in 60 wheat strains, furthermore, the genetic diversity of wheat varieties were also analysized by variation analysis and cluster analysis to provide theoretical and practical guidance for matching hybrid combinations and improving the efficiency of breeding.The results showed that testing varieties in sterile spikelet had larger variation potential, ear number per spike, plant height and the character of variability were in the middle, and in the grain number spikelet number and panicle traits the variation range were small.Though variation of some characters may not accord with the requirement of the current production, the genetic resources which possessed may be the basis of particular breeding goal, so as to provide more space for parent selection. |
