Photosynthate remobilization capacity from drought-adapted common bean (Phaseolus vulgaris L.) lines can improve yield potential of interspecific populations within the secondary gene pool

  Interspecific lines obtained from crosses between common bean (Phaseolus vulgaris L.) and other species from its secondary gene pool have a tendency for excessive vegetative growth and low grain yield. Contrariwise, drought-adapted common bean lines have been observed to produce high yields despite low shoot biomass production. This was attributed to greater remobilization of photosynthates to grain...

Tracking fruit size increase in recombinants obtained from an interspecific cross between cultivated tomato (Solanum esculentum) and wild tomato relative (S. pimpinellifolium)

  The present study was conducted to track the progress in fruit size increment in inter-specific tomato hybrids from F1 to F12 generation. Selection was imposed at every generation and the incremental rate in single fruit size from one generation to another was obtained using relative performance difference (RPD) between successive generations. Increase in fruit size was vivid at every generation and...
