ANALYSIS ON THE FEASIBILITY OF PRODUCING HYBRID WHEAT WITH GOOD QUALITY BY USING A CHEMICAL HYBRIDIZING AGENT |
| |
| Abstract: | Seven varieties which were treated with a chemical hybridizing agent (CHA) Sc2053 were used as female parents to make combinations with a good quality variety “R344”. The heterosis performance of the CHA hybrid wheat in agronomic and qualitative characteristics were analyzed.All the hybrids showed significant mid and best parent heterosis for grain yield per plant and yield components. Among yield components,spikes per plant and 1000 kernel weight proved to be important traits and may explain the superiority of the hybrids over their parents. The high yield hybrids also showed higher biomass than their parent, while most of hybrids did not show the best parent heterosis for palnt height.The heterosis for qualitative traits varied with different combinations.Most of the hybrids showed mid parent heterosis for protein yield per plant,flour protein content,gluten content and sedimentation value,only a few showed best parent heterosis. It is peasible to develop and produce CHA hybrid wheat with both higher yield and good quality . |
