This study focus on developing new salinity tolerance and high yielding rice lines, using markers assisted backrossing (MABC). Salinity stress is one of the most severe constraints limiting rice production worldwide. These (2015). 1. for salt tolerance has been normally carried out at the seedling stage and under NaCl stress3l. Journal of Agricultural Technology. In 2007, licence of mutant variety Khang Dan Dot bien (origin is KD18) was successfully transferred on Centural Seed Company. 1High Agricultural Technology Research Institute for Mekong Delta, Vietnam 2Institute of Agricultural Sciences for Southern Vietnam, Ho Chi Minh City, Vietnam *Corresponding authors’ email addresses: ntlang.prof@gmail.com, buu.bc@iasvn.org SUMMARY Salinity stress is a major limitation to rice (Oryza sativa L.) yields and its stability, Recently, Aslam and Qureshi6l and Ahmed and Gupta2l have introduced a screening method for salinity tolerance at the germination stage, and using this method, Tobita et al.18) analysed the geographical distribution of salt tolerance in rice. Plant Name: Information: King Alfred® Dianella caerulea ‘JOHN316’ PBR A tidy plant with purple and yellow flowers from September to March. Using marker-assisted backcrossing (MABC) to develop a new salt tolerance rice cultivar is one of the feasible methods to cope with these devastating changes. Agricultural Genetics Institute-Vietnam. Can Goldfish and Koi be Housed Together? A company started by two 24-year-old scientists wants to produce salt-tolerant rice and floating ocean farms by 2021, with small pilot farms by the end of 2020. Fancy goldfish are not as good of an option for either the fast kind of goldfish or koi … Nyalla® Lomandra longifolia ‘LM400’ PBR Evergreen, with fine leaf foliage that looks like a grass tree, but is trunkless, faster growing and doesn’t need annual trimming. Despite their differences, slim-bodied goldfish and koi can make wonderful companions. Phuong Dong University Luu M.C., Phung T.Q., Luu T.N.H. 11(8): 2263-2272. However, the production and the cultivating areas are adversely affected from the threats of devastation caused by the rise of sea level. Breeding for the Salinity Tolerance Rice Variety in Vietnam. ance, salinity tolerance varieties comprising CM-1, CM-2, CM-3, cold tolerance varieties including DT-10, DT11, DT13, Khang dan Dot bien, DT37, DT3 having short growth, good quality, high yield and good resis-tance. In this study, we reviewed global patterns of salinity tolerance across a broad range of freshwater organisms. Salinization of freshwater ecosystems represents a potential threat to biodiversity, but the distribution of salinity tolerance among freshwater organisms and its functional consequences are understudied. This study focus on developing new rice varieties which are salt tolerant combine with high Abstract Plasticity in salt tolerance can be crucial for successful biological invasions of novel habitats by marine gastropods. Thus, the development of salt-tolerant rice promises to deal with increasing food demand due to climate change effects. Total of 500 SSR markers on 12 rice chromosomes were screened for parental polymorphic markers. Rice is a stable food in Vietnam and plays a key role in the economy of the country. and Le H.H. Salinity may increase to beyond 40 ppt and thus retard growth. Both are athletic, strong swimmers with a good tolerance to cold weather. 2. This should be taken into consideration when brackishwater species are used since salinity may increase above their limit of tolerance.
