Abstract

The objective of this study was to identify the adaptability of twelve artemisia mutant genotypes, which were planted in three locations with different altitude, as a result of gamma irradiation. Randomized Complete Block Design (RCBD) was applied in this research with three replications as blocks. The genotypes 1B, 1C, 1D, 2, 3, 4, 5A, 6B, 7A, 8, 14, 15 and two control genotypes as parent genotype from seed and from in vitro were used. The genotypes were planted in three different locations such as Mount Putri, Cianjur (1450 m above sea level), Pacet, Cianjur (950 m above sea level) and Cicurug, Sukabumi (540 m above sea level). Based on the method of postdictive and predictive success, the model used was AMMI2 which was able to explain up to 100% of interaction-influenced variation. The genotypes which were found stabile and adaptive in these three locations were 1B, 1C, 1D, 6B and 15. Genotypes 3 and 7A were adaptive specifically in Pacet area, 5A was adaptive for Gunung Putri while genotype 4 was for Cicurug only.Keywords: AMMI, Artemisia annua, mutant genotype, adaptability

Abstract

The drought stress tolerant and high yielding rice is needed in upland rice system. The changing global climate makes dry season longer, resulting in the reduction of rice production. There should be an effort to introduce new variety of high-yielding and drought tolerant rice.  In this attempt, research was conducted to improve the genetic of Indica rice, particularly Gajahmungkur, Towuti and IR 64 varieties in order to find the somaclones with the characteristics above. As an approach, gamma-ray mutative induction was applied to be followed by selection in PEG. The regenerated shoot from the irradiated callus was then selected and acclimatisized in the greenhouse to obtain eighty three somaclones from the three varieties. PEG (molecular weight 6000) was applied to obtain the drought-tolerant somaclone. PEG was a selective agent used by which populations could be selected in a short time. Treatment with  20% PEG (equals to osmotic potential 1.2 Mpa) on the rice produced 16 somaclones from Gajahmungkur, 12 from Towuti and 18 from IR 64 putatively drought tolerant.   Key words : Oryza sativa, drought tolerance, PEG
