Okra yellow vein mosaic virus resistance
ISBN-13: 9783659459993 / Angielski / Miękka / 2013 / 316 str.
Inter-specific hybridization for yellow vein mosaic virus (YVMV) resistance followed by selection in the segregating generations is an effective method for obtaining desirable recombinants. Several wild species of cultivated okra showed high degree of YVMV resistance. However, resistant varieties developed by various research organizations by inter-specific hybridization have started showing sign of susceptibility, probably due to arrival of new virus strains. Hence, it is imperative to find diverse source of resistance to YVMV and evolve resistant varieties by suitable gene introgression programme. In this book, objective studies include initial screening of wild and cultivated types of okra for resistance to YVMV and other important diseases and pests, studying cross compatibility and inter-specific hybridization between wild and cultivated types, screening inter-specific hybrids and their parents for resistance to YVMV and other important diseases and pests, confirming the hybridity of inter-specific F1 hybrids through protein electrophoresis, evaluating biochemical basis of resistance to YVMV and development of backcrosses in resistant inter-specific F1 hybrids
