Among the event features are the wreath-laying on Dr. Gen. Florencio A. Medina monument, the Philippine Nuclear Research and Development Conference (PNRDC) which will be on hybrid mode, and several contests such as Mobile Photography, Poster Making, and NucleArt 4.0
Dr. Medina, known as the Philippine Father of Atomic Energy, is the first commissioner of the then Philippine Atomic Energy Commission, forerunner of today's PNRI. Every AEW celebration starts with wreath-laying at his statue in the presence of his family members to give honor and respect to his contributions to nuclear science and technology in the country.
The PNRDC, meanwhile, will feature research abstracts on nuclear S&T and related fields on Dec. 6 and 8. The live conference will be hybrid as researchers from all over the globe will present their recent studies virtually while the organizer-hosts will hold the event face-to-face at PNRI.
Other guests in the AEW are Filipino scientists, professionals, and policy makers who will either present or join discussions on the latest nuclear and radiation-related innovations as well as the preparations for the impending foray of the country into a nuclear power programme.
Overall, the event will highlight current initiatives that will prepare the country for more relevant uses of nuclear S&T in the areas of health and medicine, food, environment, and energy security in the next 50 years.
The annual AEW celebration, as mandated under Presidential Proclamation No. 1211 in 1973, aims to generate awareness of the Filipino people on the beneficial uses of nuclear science and technology.

New mutants bloom at PH nuclear agency
- Details
Mr. Fernando Aurigue, Scientist I of the DOST has been doing mutation breeding for many decades. In this photo, he shows one of the propagated mutant “calachuchi” varieties.
New mutants bloom at PH nuclear agency
DOST-PNRI developed two new varieties of Plumeria through mutation breeding. The varieties are now registered with the National Seed Industry Council (NSIC), Bureau of Plant Industry and at the Mutant Variety Database of the International Atomic Energy Agency.
More popularly known as “frangipani” or temple flower in English and “calachuchi” in Filipino, Plumeria rubra in the scientific world has new babies at the Philippine Nuclear Research Institute (PNRI) of the Department of Science and Technology (DOST). With their enhanced looks and scent, the new blooms will surely capture the hearts of flower lovers, especially the “calachuchi” fans.
Meet “Illuminance” and “Radiance,” both borne using the nuclear technique called mutation breeding. That they were bred through irradiation technology is what makes them different from the usual neighborhood “calachuchi.”
Most “calachuchis” grown today for planting onsite start as stem cuttings. Illuminance and Radiance started as seeds. But unlike hybrids, they took on a different path - they were exposed to a certain dose of gamma rays before germination to produce novel traits.
The traits of both blooms were not planned nor designed. They were the results of the effects of radiation applied to the planting material. Radiation altered or modified the plant’s’ genetic make-up which resulted in a new trait that can be preserved through vegetative propagation of the plant or inherited by its offsprings.
To ensure that the desirable traits are stable and can be passed on to the next vegetative generations, each generation was evaluated on the evident changes.
“We observed exactly the same mutated characteristics with each vegetative generation advancement for six generations,” explained Mr. Fernando B. Aurigue, Scientist I and lead of the Ornamental Plant Mutation Breeding project. “For “calachuchi,” six vegetative generation advancements took three to six years.”
Improved desirable traits
“Illuminance” and “Radiance” have improved traits in growth habit, flower color, and scent.
The original and non-irradiated control Plumeria rubra has white blooms with yellow center. They also bear the scent that is associated with deaths and funerals that is most prominent at night until morning.
But not for these new babies. As an improved version, the flowers of Illuminance look very elegant and feminine. The white petals are lined with a purple-pink swatch that vanishes into the middle of the flower with a yellow center.
Meanwhile, Radiance glows with its summery look-- pure white petals with a radiant yellow center.
Both have a delectably sweet scent. The trees are compact in growth habit and bloom almost all year round with peak of flowering during the dry months.
Long, careful study
But a big load of patience is required in mutation breeding. Greater effort was most needed for generation advancement and stability testing parts of the study.
“The experiment actually started in 2009,” revealed Sir Nanding, as he is fondly called at PNRI. “We tried different doses of gamma rays and determined the best one.”
“At 30 Gray, traits are already evident. At higher doses, the seedlings died or the seeds did not germinate at all,” he said.
Gray is a unit of radiation dose. A dose of 1 Gy is equivalent to a unit of energy or joule deposited in a kilogram of a substance (or matter). For example, a chest X-ray comprises 20 microGrays (µGy), while eating a banana which naturally contains potassium-40 gives 0.1 µGy.
The right radiation dose applied in the right conditions produced the beautiful mutants whose traits consistently came through across at least six vegetative generations.
“Plumeria ‘Illuminance’ (NSIC 2021 Or 101) and P. ‘Radiance’ (NSIC 2021 Or 102) are now registered with the IAEA Mutant Variety Database with ID numbers 4943 and 4944, respectively,” informed Sir Nanding.
He likewise acknowledges the help of Mr. Luis Mauricio Alfonzo-Godoy of IAEA for facilitating the processing of the Mutant Variety Registration Forms.
