The methodology of honeycomb mass selection in yield improvement of alfalfa

Celami A.

Honeycomb mass selection design have been used in a genetic broad based ecotype of Alfalfa to assess its efficiency in yield improvement through two cycles of selection. The selection intensities used were: 14.26, 7.69 and 5.26 in the first and 14.26, 7.69, 5.26, 2, 3.22, 2.77 in the second cycle of selection. According to the results obtained from field trials it was concluded that the application of this design was effective in improvement of yield by 13.5 in first cycle. In the second cycle only the first 'selection' outyielded the initial population Heronia P2. The mean gain for two cycles of selection was 6.5. The selection intensities when select from yield must be maintained in the borders 10-14.
