Description

The influence of pollinating mode and of conditions for seed formation was studied on 30 clones of different genetic constitution. The average yields per plant have changed markedly under the influence of environmental conditions, especially of variable precipitation.

The correlation between the years was positive and significant. The number of flowers forming pods and also the average number of seeds per flower and per pod are in close relation to the seed yield of the individual plants, not only under self-pollination but also under open pollination. In the dry year of 1973, the correlation coef­ficients under open pollination were lower for all characters.
