In the case of SCA the results were the same: we could not find any very different
results of SCA in either combination. There are relatively higher values of SCA for pod
per plant in 2x3 and 4x5 combination, and for pod- length in 1x6 and 4x7, and for seed
number of pod in 2x7 and 3x5 combinations. The standard deviations are higher in
number of pod per plant.
DISCUSSION
The parents in the diallel were selected consciously. Our aim is to produce an earlier
variety with high yielding capacity thus these results just are the part of the whole
experiment, which can help us to breed the new varieteies.
Predominance of additive effects in tested features were typical excluding pod per
plant thus the features can be improved any further in the respective combinations.
These results are similar to other author's results. The reports on inheritance of yield-
related traits in garden pea are variable as apparent from gene action that was reported
to be additive (Rathore et al., 1995) and epistatic (Narsinghani et al., 1982) for pods per
plant, additive (Singh and Singh, 1991) and non additive (Srivastava and Singh, 1988)
for seeds per pod.
The studied traits, which has higher GCA effects-values has higher phenotypic
values. According to our results the parents of the best phenotypic values combination
are the parents with the best GCA values parents (Table 4.) The best variety was the
Foremos in the pod length and seed per pod traits, and these were accompained the
highest GCA values. In the combination with the best phenotypic values, the one parent
is the Foremos (3.). Since the Foremos an earlier variety with long pod length (8-10 cm)
and many seed per pod (8-9). These traits are just in a few combination have improving
effects. These improving effects aren't so large rate, that we can stabilize the trait in the
