Abstract/ Executive Summary:

Twelve well known mango varieties of Bangladesh (Surjapuri, Ashwina, Kalia, Deori, Fazli, Langra, Lota Bombai, BARI Aam-l, Gopalbhog, Bombai, Khirsapat, and Rani Passand) planted in the research farm of the Horticulture Research Centre of BARI at Joydebpur were evaluated in respect of tree growth, flowering and harvesting time, yield per tree, and quantitative and qualitative characteristics of leaf, inflorescence and fruit. Susceptibility of the varieties to insects and diseases was also observed. Full bloom in all the varieties took place between 26 February to 02 March. Fruits of the varieties were harvested between 24 May and 10 July. The variety Deori was the earliest and Ashwina was the latest in respect of harvesting time. The maximum number of fruits/tree (300) and yield/tree (37.40kg) were produced by Kalia and Ashwina, respectively. The highest fruit weight (315.00g) was obtained from Fazli followed by Ashwina (220.00g), Bombai (207.00g) and Langra (200.00g). The highest percentage of edible portion was recorded in Ashwina (76.00%) followed by Langra (73.00%), Fazli (72.00%, Kalia (71.00%, Bombai (70.50%), Khirsapat (68.50%), Gopalbhog (68.50), and BARI Aam-l (68.00%). TSS was found to be the highest in Khirsapat (22.00%) whcih was followed by Bombai (19.50%). Langra (18.50%), Gopalbhog and BARI Aam-l (18.00%). All of the varieties were affected by different insects and diseases in different degrees. In overall performance, the varieties Khirsapat, Gopalbhog, Langra, and BARI Aam-l were better than the others.

Start Date: 00-00-2005

End Date: 00-00-2005

Program Area: Socio-economic and Policy

Commodity: Performance

Objectives:

To select suitable varieties for growing under the climatic conditions of Gazipur.

Methodology:

The experiment was conducted at the Fruit Farm of the Horticulture Research Centre, BARI, Gazipur during the flowering season of 2005. Twelve varieties of mango, namely Surjapuri, Ashwina, Kalia, Deori, Fazli, Langra, Lota Bombai, BARI Aam-1, Gopalbhog, Bombai, Khirsapat and Rani Passand were included in this study. The experiment was laid out in a Randomized Complete Block Design (RCRD) with three replications in 1993. A single tree of each variety constituted the unit of replication. The trees were fertilized with the recommended doses of manures and fertilizers. Intercultural operations, such as weeding, ploughing, irrigation, and spraying of insecticides and fungicides were done as and when necessary. Data on tree growth, flowering and harvesting time, yield per tree as well as quantitative and qualitative characteristics of leaf, inflorescence and fruits were recorded following the 'Descriptor for Mango' published by the IBPGR in 1989. Tree volume was calculated by using the formula of Castle (1983) with slight modification.Tree volume (m³) =1/6 height x (2r)², where 2r = (East-West spread + North-South spread)/2and = 3.14. Leaf area (cm²) y = K.X, where K is constant (0.737) and X is the length X breadth of leaf. Ten well ripe fruits of each variety were harvested randomly from each tree for recording data on physico-chemical characteristics. The incidence of insect and diseases were also recorded as per "Descriptors for Mango".
