Patna: A research initiative by the Central Institute of Subtropical Horticulture (CISH), Lucknow, in collaboration with the Bihar State Biodiversity Council, is set to bring a major boost to mango farmers in Bihar. Scientists have identified 23 distinct varieties of the indigenous ‘Biju’ mango, known for their superior size and sweetness, and plan to study and promote them for commercial cultivation.
The joint research has revealed that Biju mangoes, native to Bihar, can weigh between 450 grams and a kilogram—considerably larger than most grafted varieties. Early findings also suggest the fruit has a higher sugar content, making it particularly attractive for the market. The research team will work with farmers to conserve and improve these local cultivars, aiming to enhance incomes and preserve biodiversity.
Muzaffarpur district has emerged as a hotspot for these prized mangoes, with varieties discovered in areas including Meenapur, Katra, Mushahari and Saraiya. In Meenapur’s Jamin Mathiya, four unique strains of Biju have been identified, while a tree in Katra’s Amma village consistently yields fruits over 500 grams. Mushahari has produced Biju mangoes weighing up to one kilogram. In Saraiya’s Baghnagari village, a single tree bears over 2,000 fruits. Additionally, the Sepia variant from Vaishali has been found to yield 20% more fruit than conventional grafted varieties.
According to Dr T Damodaran, director of CISH, the Biju mango is well-suited to Bihar’s climatic conditions and shows natural resistance to diseases and pests. “With proper support and conservation, these varieties can significantly improve productivity and market returns for farmers,” he said.
