Evaluation of French bean (Phaseolus vulgaris L.) genotypes for seed production

Abstract

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.

Performance of bush type frenchbean varieties (Phaseolusvulgaris L.) with or without rhizobium inoculation

“…The variation in yield might be due to significant genotypic x environmental interactions as reported by Devi et al,(2015).Considering the interaction effects, Arka Komal produced the longest pod length (14.36 cm) biggest pod width (1.27 cm) and highest individual pod weight (6.86 g) when grown with Rhizobium inoculation, whereas, shortest pod length (12.61 cm) was observed in Victoria and smallest pod width (0.61 cm) and lowest individual pod weight (3.61 g) were noticed in Falguni when grown without Rhizobium inoculation treatment. Higher number of pods per plant was obtained from Special Jhhati Beans (24.26) followed by Nandini (20.32),Victoria (18.69) and was lowest in Falguni (12.84).The findings of genotypic variation in number of pods per plant is also supported by Das et al, (2014) and Yadav et al, (2015) for different varieties in another experiment. The highest yield per plant (85.97 g) and total fresh pod yield (23.05 tonnes/ha) were obtained from Special Jhhati Beans when grown with Rhizobium inoculation treatment, whereas lowest yield per plant (41.84 g) and total fresh pod yield (13.77 tonnes/ha) in Falguni were recorded when grown without Rhizobium inoculation treatment.…”

“…The variation in pod length, pod width and individual pod weight of French bean varieties observed in the present study may be due to their inherited traits and to some extent by environmental factors. Similarly, variability for pod length and pod width in different varieties of French bean was also reported by Kumar et al,(2014) and Das et al, (2014).Variation in number of pods per plant in different varieties was reported by Ramana et al, (2010) in frenchbean and Sharma et al, (2014) Das et al, (2014) in French bean with different varieties. The variation in yield might be due to significant genotypic x environmental interactions as reported by Devi et al,(2015).Considering the interaction effects, Arka Komal produced the longest pod length (14.36 cm) biggest pod width (1.27 cm) and highest individual pod weight (6.86 g) when grown with Rhizobium inoculation, whereas, shortest pod length (12.61 cm) was observed in Victoria and smallest pod width (0.61 cm) and lowest individual pod weight (3.61 g) were noticed in Falguni when grown without Rhizobium inoculation treatment.…”

Performance of French Bean (Phaseolus vulgaris L.) Genotypes In Sylhet Region of Bangladesh

“…The lowest value (38.67 g) of 100-seed weight was recorded in BARI Jharsheem-1. The genotypic differences on 100-seed weight in French bean have also been reported by Das et al (2014). The highest seed yield of French bean was found in the line Local-5 (3.48 t ha -1 ) that was statistically similar with that of all other local lines except the Local-1.…”

Constraints and solutions of country bean (Lablab purpureus L.) Production: A review

“…In Bangladesh ( Table 2) [24,25] . Das et al (2014) [26] noted frequency of five key insects and mite infested of bean field in Bangladesh. These were aphid (Aphis craccivora Koch), flower bud and pod borer (Maruca testulalis G.), leaf miner (Cosmopteryx sp.…”

“…About 30 species of insects have been reported damaging Indian bean. The major pests include aphids, sap-sucking bugs, pod borers, leaf miners and stem fly (Das et al 2014) [26] . The major insect to common bean is stem maggot and aphid which cause the yield loss of about 37% to 100% and 37% Ochilo et al, (2011) [14] .…”
