Abstract
Advantages and disadvantages of self-fertile cultivars are discussed, and a method to avoid the complete loss of heterosis is suggested. Nine components of self-fertility related with the processes of pod and seed production were analysed from a genetic point of view. The parameters obtained suggest that transmission of self-fertility is not difficult The genetic control of these characters is also briefly presented and discussed, together with the disadvantages detected when studying it by means of F1 diallel crosses and F2 segregations. From a practical point of view, pods/node and seeds/pod (in the absence of insects) seem to be the most convenient indexes to be used to select for self-fertility, according to their correlations with the other parameters studied.
