| Abstract: | The analysis with seventeen double low elite varieties of rapeseed indicated that yield per plant had a significant positive correlation with available primary branches,available pods per plant and thousand kernel weight.The same correlation was found between available pods per plant and available primary or secondary branches.The thousand kernel weight had a significant negative correlations with available primary branches,available secondary branches and available pods per plant. |
