Five high-yielding varieties (HYVs) of mango have been developed by the Horticulture Centre under the Agriculture Extension Directorate at Kewatkhali in Mymensingh, Bangladesh. The varieties are Amropali, Ratna, Sindhu, Mishra Special and Hybrid-10. The five new varieties of mango were developed by cultivating the fruit on an experimental basis. Officials at the Horticulture Centre said that the mango varieties were developed by grafting the branches of different species of foreign mango trees with the local variety. Already, saplings of the new HYVs have been distributed for cultivation in the fields. The speciality of these five new varieties of the fruit is that although the trees will not gain the usual height, the fruit will be fleshy and sweeter than known varieties like Langra and Gopalbhog. The seeds will also be smaller. According to a report in the Bangladesh Observer, the Horticulture Centre has also developed other hybrid varieties of fruit like the jalpai , kamranga and jamrul .
