Genetic divergence of guava (Psidium guajava L.) genotypes in Bangladesh

A noticeable variation is present among the guava (Psidium guajava L.) genotypes available in Bangladesh. Thirty-three (25 indigenous, 5 released, and 3 exotic) of were used ex-situ conditions from different locations Chattagram, Brahmanbaria, Pirojpur, Gazipur districts assessed based on 10 traits to know their genetic diversity. The measured number flowers, fruits, harvested fruits per plant, single fruit weight (g), seeds/fruits, thousand seed vitamin C, total sugar content, yield/plant (kg). Twenty-one showed 100-400 g weight, 12 20-100 g. genotype G14 (BARI Peyara-1) produced highest (131.04 kg) followed by G24 (PG Muk-005) G 23 yielded 65.49 kg 64.62 kg, respectively. above 250 mg/100g C content. Above 42% (14 genotypes) contained content over 5%. first two axes accounted 58.8% traits. Based heatmap analysis, cluster-IV represents a high value containing plant. 14, G17 Peyara-4), G21 Sit-003), G23, G24, G29 (Thai Peyara-3) might be considered best morpho-biochemical characteristics. Many are significant economic importance could as breeding targets increase yield quality. Therefore, will an excellent source for future crop improvements. SAARC J. Agric., 20(1): 15-28 (2022)
