Crops and consumer preferences of 20 local rice genetic resources of Yogyakarta, Indonesia

The local genetic resourcesof rice was natural resources that need to be preserved from extinction. The aim of this research was to know the crop's preference and consumer preferences of20 local rice of genetic resources from Yogyakarta. The study was conducted from July to October 2016 in Selomartani, Kalasan, Sleman, Yogyakarta, Indonesia. The research was conducted by planting 20 local rice genetic resources of repeated twice, using Integrated Crop management (ICM) with legowo planting system. Observations of plant performance included plant height, plant age, number of productive tillers, panicle length, leaf length, leaf width, grain amount of fill per panicle, 1000 grain weight and production. Data were analyzed using SAS software version 9.Consumer preferences for cropping are conducted directly with farmer, extension and related stakeholders' meetings on the level of consumer preference for agronomic cultivation of the local rice crops and to disseminate of specific local rice variety in Yogyakarta. Consumers/farmers meeting participants select the preferred local genetic resources of plant performance including age, plant height, number of tillers, panicles and production. Result of local rice consumers' preference in Yogyakarta by calculating frequency of emergence of local rice varieties selected and presented in histogram form.The results showed that the local rice varieties tested were found to differ according to the performance of the genetic potential of the Integrated Crop management (ICM) approach technology with legowo planting system. Three varieties of local rice farmers choice of crops with higher grain yield compared to Pandan Wangi (as a comparison) were "Mentiksusu", "Mentikputih" and "Gadingmlati". Four other local rice varieties with higher yields than Pandan Wangi (as a comparison) were "Lestari", "Ho-ingbatangbiru", "Sri kuning" and "Menur". Local rice varieties that have the highest yield are "Mentiksusu" varieties, 42.67% higher than Pandan Wangi (as comparison) having yield 6.42 tons/ha, with plant height 115.2 cm, number of tillers 15.6, panicle length 24.97 cm, leaf length 29.47 cm, leaf width 13 mm, grain content per panicle 127.8 and production of 6.42 tons/ha.
