Correlation studies in snapdragon (Antirrhinum majus L.)

The present study was carried out to find out the association among important quantitative characters in snapdragon. The correlation studies revealed that plant height exhibited highly significant and positive correlation with spike length, rachis length and number of seeds per pod. There exists a significant and positive relationship of number of primary branches per plant with duration of flowering and number of spikes per plant; number of spikes per plant with number of leaves per plant. Floret diameter also exhibited significant and positive correlation with number of seeds per pod and weight of seeds per plant. However, nonsignificant and positive correlation was found in characters viz., plant height with floret diameter, number of pods per spike and weight of seeds per plant; plant spread with floret diameter, number of seeds per pods and weight of seeds per plant; number of primary branches per plant with weight of seeds per plant; duration of flowering with number of spike per plant and floret diameter.
