ABDUR RAB Fourty (40) genotypes of Brinjal were studied in the experimental field of Olericulture division of Horticulture Research Centre (HRC) of Bangladesh Agricultural Research Institute, Gazipur, during September 2018 to March 2019. There was significant variation observed for all the characters within genotypes. Multivariate analysis was performed through principal component analysis(PCA), principal coordinate analysis (PCO), canonical variate analysis(CVA) and cluster analysis(CLSA). As per PCA, D 2 and cluster analysis, the genotypes were grouped to five clusters. The highest inter-cluster distance was between cluster I and IV and lowest between II and III. Cluster IV showed the maximum intra-cluster distance and I showed the lowest. Regarding agronomic performance, different characters contribute increasing the higher yield of brinjal. The height cluster yield mean observe from cluster I which include genotype SM 359, SM 362, SM 364, SM 367, SM 378 used as advance line. This advance line further used for development of high yielding OP (Open pollinated) variety in future. Due to the higher inter cluster distance, the genotypes BARI Begun-6 from cluster I, SM 359, SM 362, SM 364, SM 367, SM 378 from cluster II and SM 323, SM 351, SM 365, SM 373, SM 387, SM 393, SM 398, SM 399, BARI Begun-7, BARI Begun -8 from cluster IV would be suitable for efficient hybridization programme.

The experiment consisted of two factors. Factor A: Sugar Concentrations per 500g fruit; S 1 :200g sugar; S 2 :250g sugar; S 3 :300g sugar and Factor B: Preservatives per 500g fruit; P 0 :no preservative; P 1 :sodium benzoate :potassium metabisulphite S 2 P 2 was found the best in case of jam and S 3 ii P 2 was found the best in case of jelly.

ALIFA An experiment was conducted on the aspect of quality and shelf life of mango through postharvest preservatives and packaging. This study was carried out at the Postharvest laboratory of Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka. The experiment was laid out in a Completely Randomized Design. Seven postharvest preservative treatments and two postharvest packaging, total 14 treatments combination were used in the present study. Different postharvest preservative treatments were T : Control (without preservative), T 1 : 1-methylcyclopropene (1-MCP) dips, T : chitosan dips, T 3 : calcium chloride dips, T : 1-methylcyclopropene (1-MCP) dips + chitosan dips, T 5 4 : 1-methylcyclopropene (1-MCP) dips + calcium chloride dips, T 6 : calcium chloride + chitosan dips. Two postharvest packaging: P : With perforated LDPE packaging and P : Without packaging were used. Results revealed that the lowest weight loss was found in T 0 treatment (3.78%, 5.45%, 7.05%, 8.78% and 10.50% at 3 rd , 6 th , 9 th , 12 th 4 and 15 th days after harvest, respectively) with the lowest disease incidence (%) and slower ethylene release rate (1.94 ppm/hr., 3.94 ppm/hr. and 8.17 ppm/hr. at 3 th , 6 th and 9 days after harvest, respectively) compare to other treatments. The longest shelf life (18 days) was recorded in T 4 P treatment combination. The better performance was observed in mangoes when treated with postharvest 1-methylcyclopropene (1MCP) dips + chitosan dips and postharvest packaging with perforated LDPE bags for long term storage A Thesis Submitted to The Department of Horticulture, Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE (MS) IN HORTICULTURE 2019-01-01T00:00:00Z http://localhost:8080/handle/123456789/3502 FLOWER FORCING TECHNOLOGY FOR OFF SEASON MANGO PRODUCTION AKTER, MARGINA An experiment was accomplished in the Roof top of Sher-e-Bangla Agricultural University during the period of July, 2018 to January, 2019 to adopt flower forcing technology for off season mango production. Four treatments viz. No chemical application (T 0 ), 1g PBZ/L water (T 1 ), 0.5g PBZ/L water (T 2 ), 0.25g PBZ/L water were studied in this experiment following completely randomized design with six replications (CRD). Data on flowering and fruit related parameter were taken and significant variation was observed with different treatments. Among them, maximum inflorescence number/plant (8.7), fruit number/inflorescence (4.5), fruit number/plant (30.8), harvested fruits/plant (8.3), fruit length (11.7 cm), single fruit weight (273.8 g) and yield/plant (2.3 kg) was found in T 2 treatment whereas maximum days required to first flowering (100.0 days), minimum inflorescence number/plant (3.2), fruit number/inflorescence (3.0), fruit number/plant (12.3) recorded in T 3 treatment and no flowering observed in control. So, it can be concluded that, significant treatment effects were observed on different parameters and T 2 treatment (0.5g PBZ/L water) gave best results. Therefore, it can also be articulated that a new flower forcing technology is developed and it will be potential for off season mango production.
