EFFICIENCY OF SOME SELECTION PROCEDURES FOR YIELD IN FIELD BEAN (Vicia faba L.)
Safia Ali Mohamed Dorgham;
Abstract
This study was canied out during the period of
1998/1999, 1999/2000 and 2000/2001 growing seasons at Etay E1-Baroud Agricultural Research Station, Behaira Governorate, Egypt. The objective of this study was to estimate the response to different methods of plant breeding i.e., pedigree, bulk and single pod descent. Also, direct and indirect selection criteria for increased seed yield were canied out. A selection intensity of
5% was used with direct selection (selection for seed yield it self) and with indirect selection using the tlu•ee criteria, i.e. no. of seeds/pod, no of pods/plant and 100-seed weight. The genetic parameters were estimated in F3, F4 and F5 generations.
Two F2 populations derived from the crosses (L 18 x L
103) and (G.B. x G.429) were used.
The obtained results could be summarized as follow: A. First cross (L 18 x L 103):
1. Mean squares associated with F3 and F4 families were found
to be significant for the five traits under study in the first cross line 18 x line 103.
2. Genetic gain was rather higher for number of pods/plant and seed yield/plant. Moderate gain was found for 100-seed weight and number of seeds/pod. The same trend was obtained for G.C.V. %for these traits in the F3-families.
