Introgression from wild Cicer reticulatum to cultivated chickpea for productivity and disease resistance

, : Introgression from wild Cicer reticulatum to cultivated chickpea for productivity and disease resistance. Plant breeding = Zeitschrift feur Pflanzenzuchtung 124(5): 477-480

Interspecific hybridization is known to improve productivity and resistance to diseases in many crops. Therefore, an attempt was made to introgress productivity and disease resistance into chickpea from wild Cicer species. The true F1 hybrids of cultivated chickpea genotypes 'L550' and 'FGK45' with C. reticulatum were backcrossed twice to their cultivated female parents to minimize the linkage drag of undesirable wild traits. The pedigree method was followed to advance the segregating populations from straight crosses (without backcross) and BC1/BC2 generations to F5-F7. The interspecific derivatives recorded up to a 16.9% increase over the check cultivars and a 25.2% increase over the female parent in a preliminary yield evaluation trial. Of the 22 interspecific derivatives thus derived, four desi and two kabuli lines were further evaluated for seed yield in replicated trials at three diverse locations. These lines possess a high degree of resistance to wilt, foot rot and root rot diseases, and recorded a 6.1-17.0% seed yield increase over the best check cultivars.

Multivoltine silkworm strains in Japan and their origin. Some possible mechanisms in the adaptation of tropical multivoltine races of Bombyx mori to the temperate climatic zone for sericulture in Japan are discussed from an ecogenetic viewpoint. A breeding strategy is proposed to further improve the pro...
