DEVELOPMENT OF HIGH YIELDING, YEAR-ROUND, SCENTED AND ALMOST SEEDLESS VARIETY OF LEMON
Three lemon germplasms selected from the preliminary evaluation of twenty local and exotic lemons were evaluated in two locations of Bangladesh. Through consequently three years trials, two germplasm viz. LVG-1 and LVG-2 were selected considering their agronomic performance at Mymensingh and Tangail. The LVG-1 and LVG-2 has been collected from Vietnam. It was observed that, LVG-1 was superior to other exotic genotypes and also to check variety BAU Lebu-3, reactions to major diseases and insect pest infestations were also found to be tolerant. During 2015-16, 2016-17 and 2017-18 at Mymensingh, the highest fruit yield per plant (18.1, 19.1, and 20.0 kg), vitamin C content (66.8, 65.1 and 65.9 mg 100 g-1), fruit length (7.7, 8.4 and 8.6 cm), number of fruits plant-1 (190.3, 210.3 and 254.6), juice content fruit-1 (34.1%, 32.4% and 35.5%) and the lowest seed fruit-1 (3 or 2 nos.) was recorded fromLVG-1 from all the three consecutive year and also at Tangail the highest fruit yield per plant (20.6, 19.5, and 20.1 kg), vitamin C content (67.7, 65.7 and 66.1 mg 100 g-1), fruit length (8.2, 8.5 and 7.4 cm), number of fruits plant-1 (198.6, 241.6 and 268.6), juice content fruit-1 (34.6%, 37.6% and 38.2%) and lowest seed fruit-1 (3, 4 and 4 nos.) was recorded from LVG-1compared to LVG-2 and BAU Lebu-3. Considering the better performance of fruit yield, vitamin C content, juice content and less number of seed, LVG-1 genotype was selected as a new variety (Binalebu-1) to cultivate commercially all over Bangladesh.
