Other claims from this paper (8)
- Method / resource In modified marker-assisted backcross breeding, 81.57% of the genetic background was recovered in the derivative line PBW723.
- Observation Advanced breeding lines PBW665, PBW683, PBW698 and PBW703 with different gene combinations were tested in national trials but could not be released as varieties.
- Observation PBW723 was evaluated in coordinated national trials and released for cultivation under timely sown irrigated conditions in the North Western Plain Zone of India.
- Observation The incorporated stripe rust resistance genes are susceptible to stripe rust individually.
- Observation PBW723 with both genes showed enhanced resistance to stripe rust.
- Observation Three years after release, PBW723 occupies approximately 8-9% of the cultivated area in Punjab state.
- Observation Genes from Aegilops ventricosa (Lr37/Yr17/Sr38) and Aegilops umbellulata (Lr76/Yr70) were later pyramided in PBW343.
- Recommendation The authors state that a regular inflow of diverse resistant genes, rapid mobilization to productive backgrounds and monitoring of pathogen evolution is essential to protect progress for productivity and resistance in wheat breeding.
