Wheat somaclonal variants showing earliness, improved spot blotch resistance and higher yield

摘要

Somaclones (R2, R3 and R4generations) were regenerated from immature embryos of two spring wheat varieties,HUW-206 and HUW-234. Many somaclones displayed improved earliness, enhanced resistance to spot blotch disease and increased yield over the parent. The superiority of variants for yield traits and disease resistance was established in R4 generation, confirming the possibility of wheat improvement through somaclonal variation.
