e1“In the present work radiation-induced mutation followed by in vitro culture of zygotic embryos and high osmotic pressure selection methods to improve salt tolerance in avocado are investigated”
e2“Both mutagenic (LD{sub 50} = 27-28 Gy) and selective (LD{sub 20} = 157 mM of NaCl) doses were established”

Other claims from this paper (8)
- Intervention effect Germination rates of whole embryos in vitro were higher with mature rather than immature embryos in avocado.
- Observation Almost 80% of whole-embryo plantlets were successfully acclimatized under greenhouse conditions.
- Method / resource An in vitro propagation method for avocado breeding was optimized and documented.
- Observation A mutagenic dose of gamma rays giving LD50 of 27-28 Gy was established for avocado embryos.
- Observation Putative mutant lines were developed from salt tolerant avocado rootstocks.
- Observation An avocado gene bank was established in the study.
- Recommendation The authors state that the combined methodology is an alternative to traditional breeding methods for salt tolerance in avocado.
- Recommendation The authors state that bud multiplication methods in avocado need improvement.
