RCA Project-RAS /5/056—— Mutation breeding approaches to develop new crop varieties adaptable to social development and climate change (2012-2015) Outputs & Achievements Ø 351 advanced new mutant lines Ø 28 mutant varieties officially released Ø 4 regional training courses for 96 young researchers Ø 29 national training materials/protocols Ø A web-page of Asian and Ocean Association of Plant Mutagenesis (AOAPM) established ( www.plantmutagenesis.net) for sustainability of the impact of this Project
Early Mutant Rice: BINA Dhan-14 ( Bangladesh, 2013) Ø 40 ds mature earlier than its parent and 7-10 ds earlier than the local popular short duration variety BRRI dhan28 Ø Shorter in plant height (80-85 cm) and lodging resistance Ø Average yield 7.6 ton/ha Ø 2 million hectares of potential application land and also creating scope for producing another seasonal crop (mustrad / rapeseed)
Drought Tolerant Sorghum: Pahat ( Indonesia, 2014) Ø Indonesia national sorghum mutant cv. irradiation-induced from a Chinese mutant germplasm Zhenzhu Ø 80,000 ha cultivation in 2017/2018 Ø From the lab to industry and the table
Wide Adaptable Wheat: LY502 1.02 mha ( China, 2011) 0.84 mha 2017 0.51 mha Ø High yield and good adaptability 2016 Ø Grain yield 8.2 with max. of 12.2 ton/ha 2015 Ø 2rd biggest China national wheat variety with 3.6 million ha cultivation area and 948 million additional income for farmers
Ratooning Super Rice ( China) Ø 14 Super space induced mutant rice varieties Ø High yield and blast disease resistance Ø Ratooning utilization for two harvests p Max. grain yield: 21.7 ton/ha First crop Second crop p Cultivation areas: 1.9 million ha p Farmers income : 165 million USD
