<p>To support the government policy in<br />improving soybean production, it is suggested to plant early<br />maturing (<80 days), drought tolerant and high yielding<br />varieties to be applied in the cropping system of rice-ricesoybean<br />and rice-rice-rice-soybean in lowland, and in<br />dryland cropping system of rice-soybean or rice-other<br />palawija crops. Mutation breeding in soybean for early<br />maturity and high productivity in soybean can be applied to<br />obtain some new varieties. The breeding procedures<br />included selection using bulk method for M1 population,<br />followed by the pedigree method for M2-M5 generations.<br />Evaluation of uniformity (homozygous) of lines is done on<br />the M4 generation. Yield and adaption testing are conducted<br />during M5-M8 generations. Through mutation breeding early<br />maturity soybean varieties were released elsewhere. In<br />national research institutes such as The National Nuclear<br />Energy Agency (Batan) Indonesia, soybean mutation breeding<br />activities were begun since 1972, while in Indonesian<br />Center for Agricultural Biotechnology and Genetic<br />Resources Research and Development (ICABIOGRAD), it<br />was started in 2009. Batan has released two early maturing<br />soybean varieties through seed irradiation such as Tengger<br />in 1991 and Meratus in 1998. While in 2011 ICABIOGRAD<br />through irradiation of calli-derived embryo zygotic has<br />selected 50 early maturing and potentially yielding soybean<br />mutant lines. While through seed irradiation in 2012, 15<br />soybean advanced lines that matured earlier and<br />demontrated higher yield were also obtained.</p>
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.
