| Title : | EVALUATION OF BREEDING IMPROVEMENT FOR SPRING BARLEY VARIETIES IN TERMS OF YIELD AND YIELD-RELATED TRAITS |
| Abstract : | As a result of multi-year trial (2013–2017) there have been proved statistically significant breeding and genetic improvement of yield, its stability and level of manifestation of yield-related traits in the newly developed spring barley varieties Virazh, Talisman Myronivskyi, MIP Myrnyi, MIP Saliut, MIP Sotnyk, MIP Azart, and MIP Bohun. The spring barley varieties MIP Bohun and MIP Myrnyi were characterized with the optimal combination of yield and its stability according to the GGE biplot model. It was revealed that the spring barley varieties Virazh, MIP Saliut, and MIP Sotnyk had the highest genetic gain for thousand kernel weight, the variety Talisman Myronivskyi for number of productive tillers, and MIP Myrnyi for kernel number per spike and thousand kernel weight. The variety MIP Azart was differed from the other varieties in the ratio of main yield structural elements. Thus, the newly developed spring barley varieties had differences from each other in pattern of yield and yield-related traits manifestation. According to the GYT biplot model the spring barley variety MIP Bohun was the nearest to the “ideal genotype” in terms of yield*traits combination. The practical worth of the identified patterns is that the new varieties, due to the relatively different pathways of yield formation, will complement each other under unfavorable environmental factors in the production conditions. On the whole, it was shown effectiveness of combining statistical and graphical approaches to comprehensive evaluation the breeding improvement for yield and yield-related traits in new varieties compared to ones created in the previous period. |
