Abstract

Tomato (Solanum lycopersicum L.) is one of the most important vegetables in the world because of high economic value for small and medium scale farmers. Indonesia ranked 21st which contributed less than 4% of the total tomato production in the world. The development of high yield tomato was more directed to the highlands. Expansion of cultivated land to the lowlands can be an alternative to increase tomato production. The objective of this study was to obtain adaptive lines of tomatoes resulting from gamma ray irradiation that had high yield and resistance to fruit cracking tested in two different environments. This research was conducted at Leuwikopo Experimental Farm of Dramaga Bogor and in Experimental Farm of Sembilanbelas November University. The genetic material used was 10 putative mutant lines of M7 and 5 comparators were Servo, Permata, Tora, Mawar, and Warda. The lines tested in Bogor had the average fruit weight, fruit length, fruit diameter, total fruit weight, number of fruits, thickness of fruit flesh higher than the M7 lines tested in Kolaka. The M7 lines tested in Kolaka had the average fruit cracking weight character and the number of fruit cracking lower than the M7 lines tested in Bogor.
