Abstract

Abstract: The objective of this research is to produce Mentik Wangi rice with shorter flowering age, shorter rice stem and high yield. This research was conducted in Palur Village, Mojolaban Sub-district, Sukoharjo District, from April to August 2016. This research used descriptive method, performed by observing each individual and comparing to the control average. Observational variables included plant height, total number of tillers, number of productive tillers, panicle length, number of grain per panicle, panicle density index, 1, 000 filled seed weight, seed weight of cluster, flowering age and M2 mutant selection. The results showed that there were several plants indicated mutation, there were 7 plants indicate short stem mutation with height 85 cm to 97 cm. The plants which indicated short flowering age were 5 weeks after planting up to 6 weeks after planting. The mutated plants indicating of the highest number of productive tillers which were 27 up to 36. Each component result includes total number of tillers, number of productive tillers, number of grain of panicle as well as the weight of 1000 seeds in the plant indicated some mutation that has a high level of diversity in each treatment.
