Scientifically, it is named Carica papaya L. It belongs to family Caricaceae. It is the only edible species of this genus. This family includes six genera. The papaya is believed to be native to southern Mexico and neighbouring Central America. It is currently cultivated in Florida, Hawaii, Eastern British Africa, South Africa, Sri Lanka, India, Canary Islands, Malaysia and Australia. It is now present in every tropical and subtropical country. India, Brazil, Indonesia, Nigeria, and Mexico are the world's biggest producers of papaya. India is the leading papaya producing country in the world. Papayas, which are high in vitamins A and C and calcium, are often used fresh in fruit salads and desserts, as well as prepared in juices and jams or dried. Some South East Asian dishes call for the unripe fruits to be cooked and used as vegetables. Papayas produce an enzyme, papain, which aids in digestion. The fruits can be consumed as fruit when mature and as vegetable when immature. Oral consumption of Carica papaya L. extract leaves is found to increase the platelet levels as early as 24 hours with a significant International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 10 (2017) pp. 1638-1642 Journal homepage: http://www.ijcmas.com An experiment was conducted to study the effect of sucrose concentration in MS basal media on shoot proliferation of papaya using shoot tip and axillary bud as explant. The experiment was conducted in Completely Randomized Design with eleven treatments and three replications. The aim of the experiment was to study the effect of media sucrose concentration on shoot proliferation while using shoot tip and axillary bud as explant. The different parameters taken for study were number of shoots per explant, length of shoot (cm) and culture response (%). Maximum number of shoots, maximum shoot length, maximum culture response (%) was observed in media having 30g/l sucrose while culturing both the explants. Minimum number of shoots per explants, minimum shoot length, minimum culture response was noticed in media with 10 g/l sucrose in both shoot tip and axillary bud explants. The different parameters under study exhibited an increasing trend when the sucrose concentration increased from 10g/l to 30g/l but showed a decreasing trend in parameters under study when sucrose concentration was increased further. The most suitable sucrose concentration for shoot proliferation was found to be 30g/l. Keywords Sucrose, Shoot tip, Axillary bud, Shoot proliferation, Culture response.
