MOLECULAR AND MORPHOLOGICAL DIVERSITY WITH BIOTIC STRESS RESISTANCES OF HIGH 1000-GRAIN WEIGHT SYNTHETIC HEXAPLOID WHEATS

摘要: Accumulation of favorable characteristics from the genetic resources Triticeae and their exploitation for bread wheat improvement has always been main thrust breeding programs. Harnessing diversity yield contributing recently diverted attention breeders to utilize synthetic hexaploids (SHs) in programs where one factor being exploited is high thousand grain weight present SHs. This requires generating a wide array data economically important descriptors which will ultimately permit acceptance with traits. In investigation having higher are characterized elucidated prove that synthetics 1000-grain had different makeup substantiate view utilization SHs widen base bred derivatives leading future varietal development. Of morphological parameters days flowering/days physiological maturity plant height selection progeny advance. Coupled 1000 kernel these have identified cover both irrigated rainfed (drought) cultivation areas. All studied karnal bunt resistance 62% possessed prevailing strains stripe rust make them available improve potential areas two biotic stresses production constraints. Further approach also discussed.
