The experiment was conducted at the field laboratory of the Department of Genetics and Plant Breeding, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2008 to March 2009 to estimate the genetic diversity of exotic and local onion. Ten genotypes of onion were evaluated for 16 characters in a randomized complete block design to study the genetic divergence through multivariate analysis. Ten genotypes formed three clusters. Cluster III contained maximum number of five genotypes. Cluster I and II contained three and two genotypes, respectively. The inter cluster distance was larger than the intra cluster distances. The inter cluster distance was maximum between the cluster II and III (6.336) and minimum between the cluster I and II (3.876). The intra cluster distance in the entire three clusters was more or less low, indicating that genotypes within the same cluster were closely related. Considering clustered distance and cluster mean, the intra cluster distance revealed that the genotypes Indian big (G1) and Patnai pink (G5) from the cluster II and genotypes Taherpuri, Indian medium (G1), Big single bulb (G7), Big double bulb (G8), Small single bulb (G9) and Small double bulb (G10) from the cluster III may be selected as parents for future breeding program.The Agriculturists 2015; 13(1) 26-34

Correction: On 29th April 2015 the last line of the abstract was changed from “…  the shelf life of Thai-Pangas in ice stored condition is 18 days for filleted and 21 days for the whole fish.” TO “…the shelf life of Thai-Pangas in ice stored condition is 21 days and 18 days for the whole fish and fillets, respectively.”  The page numbers of this article were also changed from 175-181 to 177-183..  A comparative study on the shelf life of whole fish and fillet of cultured striped catfish (Pangasianodon hypophthalmus ) under ice storage condition was carried out by determining organoleptic and biochemical aspects in the month of September and October. It was found that shelf life of whole fish was 21 days where as fillet had slightly lower of 18 days shelf life. Value of pH changed from 7.07 to 6.97 after 24 days for whole fish and 6.88 for fillet after 21 days at the termination of experiment, pH remained to 6.5 for fillet after 18 days of ice storage. TVB-N value increased from an initial value of 1.68 mg/100g to 28.83 mg/100g in 21 days in whole fish and finally to rejection value of 35.89 mg/100g at the end of 24 days storage period. As for fillets TVB-N value was at acceptable level of 24.79 mg/100g until 18 days of storage at same condition. Myofibriller protein solubility gradually decreased with storage period for both whole fish and fillets. The results of this study indicated that in regard to organoleptic and biochemical aspects the shelf life of Thai-Pangas in ice stored condition is 18 days for filleted and 21 days for the whole fish.Res.

A comparative technical and economic analysis of two communitybased seasonal floodplains (Khirai and Angrail) of Daudkandi Upazila, Comilla during 2008 to 2010, are represented in this paper. The two floodplains differed mainly in management and fish production which were related to capital investment, variable cost, share of profits and proportional reimbursement to the fishers. Local management committees have been developed in each floodplain with significant differences. Average 142 kg/ha of fish fingerlings (carps such as Catla catla, Labeo rohita, Cirrhinus cirrhosus, Labeo calbasu, Labeo bata and exotic species such as Hypopthalmicthys molitrix, Aristichthys nobilis, Cyprinus carpio, Ctenopharyngodon idella, Pungasius hypophthalmus, Barbonymus gonionotus, Oreochromis niloticus) were stocked at the varying proportions. Fish production obtained were 2.8 to 4.4 mt/ha and 1.1 to 1.3 mt/ha in Khirai and Angrail floodplain, respectively. The average cost of fish production, total income and the net income have been estimated as Tk. 209650 ± 54167.12/ha, Tk. 281306 ± 88263.42/ha and Tk. 71656 ± 35152.51/ha in Khirai floodplain and Tk. 62349 ± 5768.90/ha, Tk. 111930 ± 12711.02/ha and Tk. 49580 ± 6948.26/ha in Angrail floodplain, respectively. The benefit cost ratio (BCR) has been recorded as 1.33 and 1.79 in Khirai and Angrail floodplain, respectively. The results reveal that the fish production and economic benefit was higher in Khirai floodplain.
