dc.description.abstract There are at least 19 major groups of local tidal rice cultivars distributed in Pelalawan District which were not pure. This study aimed to report the progress of collaboration research among Riau AIAT, Pelalawan District Government and farmers has developed in situ and ex situ conservation of the local tidal rice cultivars from the year 2007 to 2018. Positive mass selection in Karya population has resulted in KN1-79 line with a yield potential of 6.74 t/ha dry milled grain (DMG), whereas in Cekau population has resulted in C1/KB line with a yield potential of 8.60 t/ha DMG. KN1-79 and C1/KB line have been released as Karya Pelalawan variety and Cekau Pelalawan variety, respectively. Both varieties have been registered by Center of Plant Variety Protection. The drawback of these local cultivars is late in maturity. Karya Pelalawan was crossed to Fatmawati and produced varieties Bono Pelalawan and Mendol Pelalawan which have early maturity character. Cekau 34 was crossed with Cisantana and produced Inpara Pelalawan with new characters such as early maturing, aromatic grain and tolerant to iron toxicity and salinity. Participatory plant breeding has promoted the released varieties to be widely and rapidly distributed as well as easily accepted by farmers. By promoting the ownership of local cultivars to the local government, local cultivars could be as a regional identity. Thus, it has been shown that Pelalawan District Government was actively involved in the development of released cultivars derived from local rice cultivars. en_US
