The main reasons for this perference are the absence of a dire...

Variability in breeding programmes for self-fertilised crops is created by crossing, and if the value of the crosses cannot be predicted in advance then this uncertainty means that a strategy of making many crosses is appropriate. However, since there is a limit to the capacity of a breeding programme, the more crosses that are made the smaller the size of each cross (F2 population size or numb...

The purpose of this study was to investigate the advantages and disadvantages of Participatory Plant Breeding (PPB). Seventy-six breeders were randomly selected from among 95 breeders who were working at the Seed and Plant Improvement Institute, Karaj, Iran. Data were collected by a questionnaire as the main data collection instrument. The face and content validity of the questionnaire was appr...
