Abstract

The improvement of low nitrogen tolerant hybrid maize face on genotype x environment the genotype x environment interaction caused a genotype unable to maintain its appearance under suboptimal conditions. it caused the breeders difficult to choose varieties that are stable at optimal and suboptimal conditions. The using of simultaneous stability analysis methods can provide more authentic stability information. This study aims to 1) determine the yield stability of the promising low N tolerance hybrid maize varieties, 2) to obtain varieties that have high yield and stability and under optimal and sub-optimal conditions. This research was conducted at Bajeng Experimental farm, Gowa, South Sulawesi. The research was arranged in a split-plot design with two replications. Three levels of fertilizer N (N0 = 0 kg N ha-1, N1 = 100 kg N ha-1 and N2 = 200 kg N ha-1) as the main plot and 39 genotypes of maize (36 hybrids resulting from crosses of low N and 3 checks varieties Nasa 29, Bisi 18 and Jakorin 1) as the subplot. The variable measured was grain yield. The yield stability analyses were performed by Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, and GGE Biplot methods. The results showed that there were no genotypes stable in overall the four methods, but three genotypes considered as stable genotype based on two methods. H5, H6 and H15 genotype were the genotypes with high stability and high yield. The three genotypes had the opportunity to be released as a low Nitrogen tolerant maize hybrid.

Abstract

AbstractStevia (Stevia rebaudiana Bertoni) is a low-calorie alternative sweetener. The superior varieties of Stevia in Indonesia are limited. Availability of seeds plays an important role in the Stevia plant breeding program for both the selection stage and the production of high-yielding varieties. Tissue culture is the best method of Stevia propagation, but the low adaptability of plantlets causes death in the acclimatization phase. The growth and root morphology of 12 crossbreed Stevia were evaluated. A Completely Randomized Design was used with factorial consisting of two factors were Stevia genotypes (STG1,7,8,10, SBG3,4,5,7,10, SGB2,3, and SBT11) and the plant growth regulator (PGR) concentration of Paclobutrazol (PBZ) (0.1, 0.5, and 1.0 ppm) and indole acetic acid (IAA) control (0.5 and 1 ppm). The results showed that the fastest shoot emergence time was SBT11 at 0.1 and 0.5 ppm PBZ media at 4 days after culture (DAC). The fastest root emergence time was SBG7 at 0.1 and 1 ppm PBZ media (8 DAC). The highest shoots were at 1 ppm IAA media (18 cm). The highest number of shoots was STG10 at 1 ppm PBZ and SBG3 at 0.5 ppm IAA (4 shoots). The highest number of internodes was SBG5 at 0.5 ppm IAA (25 internodes). The highest number of leaves was SBG3 at 0.5 ppm IAA (57 leaves). The highest number of roots was SGB2 at 0.5 ppm PBZ (5 roots). The greenest leaf color was SBG7 at 1 ppm PBZ media. The PBZ accelerated the emergence of shoots and roots and the number of roots.Keywords: Genotype, Interaction, in vitro, Paclobutrazol, Stevia. AbstrakStevia (Stevia rebaudiana Bertoni) merupakan sumber pemanis alternatif berkalori rendah.
