Fruit morphological characters of winter season guava under eastern plateau of India: Basis of commercial selection

Thirty two guava genotypes were evaluated at ICAR-RCER, Research Centre Ranchi, on the basis of winter production during 2009-10. The fruit bud differenciation took place in growing vegetative bud and the differences between peak flowering and peak harvesting were about to 4 months for all cultivars. The eight cultivars like Mild Fleshed, Chittidar Alllabad Safeda, Sardar, CHG-1, CHG-2, Kairala Seedling and Nasik were very promising under eastern plateau and hill region. To sudy of the botany of these crop had emense imporatance to breeder, researcher and students. The maximum fruit weight was recored in cultivar Chittidar 265.67g, followed by Sardar (234.3g) and Allahabad Safeda (232.0g). The maximum TSS of the fruit was found in cv.Chittidar 13.870B while the maximum acorbic acid was found in cv. Florida Fleshed which had 358.67 mg/100 g pulp being comparable with Kairala Seedling (357.67 mg/100g pulp). The maximum seed cavity diameter was found in Sardar and Sangam, which are 7.24 cm. The former also exhibited maximum weight of seed cavity tissue (95.98g) followed by Mild Fleshed (95.70g) and Chittidar (75.23g). Very small seed was found in cv. Florida Fleshed (seed no.443.40) as compared to Allahabad Safeda which produced soft and big seeds (no.91.38). Regarding shape of the fruit, cv.Nasik was pyriform whreas CHG-1, CHG-2, Mild Fleshed, Kairal Seedling and Allahabad Safeda were round while Chittiar but oval.
