An experimental study was conducted during 2011/2012 and 2012/2013 at Horticulture Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Monhanpur, Nadia, West Bengal, India, to evaluate the performance of fourteen different bush type French bean genotypes for seed yield and to study varietal characterization based on plant morphology. The genotypes, studied under this experiment were namely, Abhay, Shillong Local-3, Arjun, Selection-9, Arka Anoop, Arka Komal, Badshah, Anupam, Arka Suvidha, Falguni, Sonali, Local, Victoria and Vaishnavi-264. From overall point of view of the outcome of the experiment, it has been revealed that genotype with relatively bolder seeds with more number of seeds per pod, and higher bearing capacity per plant generally gives higher seed yield. Among the genotypes under study, Arka Suvidha was the best one as it produced the highest seed yield (2180.92 kg/ha) and relatively good plant vigour and fairly high seed vigour index (2944.38). Falguni and Mohanpur Local also can be considered promising once for seed production point of view.

Eighteen genotypes of french bean were evaluated for genetic variability and correlation studies for pod yield and its attributing characters. Both GCV and PCV corresponded closely for all the characters indicating low environmental influence. Highest GCV and PCV were recorded for seed weight per pod (145.12 % and 144.87%, respectively). The highest heritability estimate was observed for number of pods per plant (99.71 %). Pod yield per plant was significantly and positively correlated with number of pods per plant, flower per inflorescence, pod set per inflorescence, plant height and number of leaves per plant. Six characters viz., number of pods per plant (0.917), pod girth (0.791), plant height (0.765), flowers per inflorescence (0.529), pod length (0.284) and days to first flowering (0.134) had high and positive direct effect on pod yield. Therefore, plant height, flower per inflorescence and number of pods per plant emerged as the three most important characters influencing pod yield and selection based on these characters may improve the pod yield.
