Developing of drought tolerant hybrid rice varieties requires parental lines which have tolerance to drought. Polyethylene glycol (PEG) has been widely used as an osmotic solution for detecting drought 58025B, GMJ 14B, IR 80154B, GMJ 15B, R 3, PK 90, dan PK 12.

PENDAHULUANKekeringan merupakan salah satu cekaman abiotik yang dapat menyebabkan penurunan hasil dan kualitas gabah padi (Pandey dan Bhandari, 2008). Kehilangan hasil disebabkan oleh cekaman kekeringan diperkirakan mencapai 58% (Ouk et al., 2006). Oleh karena itu, menjadi tantangan bagi pemulia untuk merakit varietas padi toleran cekaman kekeringan sekaligus memiliki potensi hasil tinggi.Teknologi padi hibrida merupakan alternatif untuk mencapai potensi hasil tinggi pada kondisi optimum
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
