Development of Timor local red peanut with multi gamma irradiation technique for obtaining several superior mutant cultivars that tolerant of drought stress, disease pests, and high production

Abstract

The main problem studied in this research is the development of local Timor red peanuts using multigamma irradiation. This study aims to develop local Timo red peanut varieties through breeding using standard multi-gamma irradiation and careful selection to obtain superior mutant cultivars. Research methods include: Irradiation, observation, sampling, selection, purification, comparative, and interpretation. The results obtained: The development of local Timor red peanuts varieties through breeding with multigamma irradiation techniques and careful selection resulted in superior mutant cultivars that could adapt to several abiotic and biotic conditions and significantly increased production. The use of multigamma irradiation in the development of local Timor red peanuts resulted in three varieties of selected high yielding mutant varieties with relatively similar production and significantly increased compared to the parent variety. The average total percentage increase in production for the three varieties of selected high yielding mutant varieties resulting from multigamma irradiation was 49.16% with an average total dry seed moisture content of 11.07%.
