De novo super-early progeny in interspecific crosses Pisum sativum L. × P. fulvum Sibth. et Sm

Abstract Earliness in crop plants has a crucial role in avoiding the stress of drought and heat, which are the most important challenging stressors in crop production and are predicted to increase in the near future due to global warming. Furthermore, it provides a guarantee of vegetable production...
