Correlation and performance evaluation of french bean (Phaseolus vulgaris L.) varieties

Correlation and performance evaluation of french bean (Phaseolus vulgaris L.) varieties were studied for growth, yield and yield attributing characters. The experiment involving twelve varieties was laid out at the Research Block of Vegetable Section in Sector No.1, University of Horticultural Sciences, Bagalkot (Karnataka) during Rabi season of 2012 in a randomized block design with three replications. Among the varieties studied, Arka Anoop was better with respect to growth, yield and yield attributing characters followed by Best of All and Arka Komal. Correlation studies are important to know the interrelationship among the characters. This also gives fair idea of contribution of different characters towards yield. Correlation studies revealed that pod yield per hectare exhibited significant positive correlation with primary branches per plant, clusters per plant, pods per cluster, pods per plant, yield per plant, root nodules and dry matter content in pod at genotypic and phenotypic level while plant height, weight of ten pods, pod length and pod width showed positive association with pod yield per hectare. Days to first flowering and days to fifty per cent flowering showed negative correlation with the pod yield per hectare.
