Abstract/ Executive Summary:

Eleven genotypes of french bean (Phaseolus vulgaris L.) were screened to select a suitable one which could provide optimum yield of fresh pod, dry seed and biochemical parameters. The maximum seed yield in french bean was found in case of genotype BB-9 (2.96 t/ha) and BARI bush bean -1 (2.95 t/ha), while that of minimum was found in BB-11(1.64 t/ha). However, maximum fresh pod yield (14.25 t/ha) was found for BARI bush bean -1, followed by BARI bush bean -2 (13.23t/ha). BARI bush bean -1 required the minimum time of 88.33 days while BB-3 the maximum of 110.00 days to attain 90% pods maturity. The highest number of diseased plants were observed in BB- 5 (30.33%) and the lowest were in BARI bush bean -1 (7.33%). No significant difference (P< 0.05) in maximum protein content among the studied genotypes was observed, for example BB-15 (21.60%) and BARI bush bean -1 (21.57%). Maximum crude fiber (5.53%) was obtained from BARI bush bean -1, followed by BB-6 (5.50%), BB-20 (5.50%) and BB-5 (5.47%), which all were statistically similar. Among all the genotypes, BARI bush bean -1 showed highest yield and superior quality of french bean.

Program Area: Variety and Species

Commodity: French bean

Objectives:

The aim and objectives of this study is to select one genotype of french bean, which requires shortest time for 4 leaves stages, 90 % flowering, pod setting and maturation, gives highest yields of pods and seeds with better biochemical parameters.

Methodology:

Nine french bean genotypes with the accession numbers, BB-3, BB-5, BB-6, BB-9, BB-10, BB-11, BB-14, BB-15 and BB-20 were collected from Agronomy Division, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur. Two varieties namely BARI bush bean -1 and BARI bush bean -2 also was collected from Bangladesh Agricultural Research Institute (BARI), Gazipur. The soil samples were analyzed at the Soil Research and Development Institute (SRDI), Farmgate, Dhaka according the Fertilizer Recommendation Guide (Anomymous, 2005). Field experiment was carried out at the research field of Bangladesh Council of Scientific and Industrial Research (BCSIR), Dhaka, in the Rabi season during November 2007 to March 2008 in a randomized complete block design (RCBD) with three replications. The unit plot size was 2.0 m x 1.5 m. Cow dung was applied 6.67 t/ha and Nitrogen, phosphorous, potassium, boron and sulphur were applied as per the recommendation of Fertilizer Recommendation Guide (2005). The seeds were sown with the spacing 30 cm x15 cm in line and about 3.0 cm in depth and covered with pulverized soil and pressed gently by hand (Mozumder 2002). The sowing was done on 20 November, 2007 and then the plots were watered slightly in the line to supply sufficient moisture for quick germination. Weeding was done at 15 days interval. The crop was protected by spraying Malathion 57 EC @ 2 ml/L as per recommendation of BARI (Anomymous, 1995). Furrow irrigation was given at an interval of 7 to 10 days depending on soil moisture content. Plant height, number of leaves, leaf area (Gardner et al.1988), leaf area index (Radford, 1967 and Watson, 1952), disease incidence (Khandaker et al. 2011), pod length, number of pods/plant, number of seeds/pod, 1000 seed weight, fresh pod yield g/plant, seed yield g/plant were measured from ten randomly selected plants for each genotype at the harvest. Data on fresh pod yield t/ha, seed yield (t/ha) and harvest index were taken from the samples of the pre-demarcated area of each plot according to Ullah (Ullah 2006). Days to 4 leaves stage, 90% flowering, pod setting and maturity of pods were counted when each physiological character was appeared in a genotype. Quantitative determination of moisture, crude protein, crude fiber, crude fat, ash and carbohydrate of dry seeds were done according to Association of Official Analytical Chemist (AOAC) (Anomymous, 2005). Statistical analysis All the data collected on various parameters were statistically analyzed by SPSS (version 13) and MS Excel programme. Analysis of variance for each of the parameters was performed by F test. Co-efficient of variation (CV%), Duncan’s Multiple Range Test (DMRT) and Least Significant Difference (LSD) test at 5% level of significance were done according to Gomez and co-warkers (Gomez and Gomez, 1984).

Achievement/Findings:

The results of the study show that out of the eleven genotypes, the highest fresh pod yield was obtained from BARI bush bean-1 (14.25 t/ha). The highest seed yield was recorded for BB-9 (2.96 t/ha), which was followed by BARI bush bean-1 (2.95 t/ha). BARI bush bean-1 took minimum time for 90% flowering (34.67 days), 90% pod setting (37.33 days), and 90% maturity of pods (88.33 days).The lowest number of diseased plant was observed in BARI bush bean-1 (7.33%). Moreover, the maximum crude protein (21.57%) and crude fiber (5.53%) were obtained from BARI bush bean-1. Therefore, BARI bush bean-1 was selected as best for its quality and yields (fresh pod and dry seed) among eleven genotypes of french bean .
