Abstract

Cultivars Granola  dan Atlantic are the best cultivars so far for farmers, due to it adaptation in Indonesia. Cv Granola is resistant to several important diseases, but the quality is low, thus only produce for vegetable purposes. Cv Atlantic is the best cultivar, in term of productivity and quality. Cv Atlantic is suitable for industry purposes, susceptible to several important diseases. Crossing between both cultivars expected to produce high yielding cultivars and adapted to Indonesian environment. The method used was crossing and germinated the seed then selected in vitro. Each germinated seed was propagated in vitro and considered as clones. In vitro selection was performed through vigour, bacterial wilt and soft rot test, as well as micro tuber production. The result of selectionwas then verified in the field. From thousands of seed germinated producing 12 selected clones, 7 clones of them were showed better then their parent in term of tuberization and micro tuber production. The clones were Atnola 1, Atnola 5, Atnola 3, Atnola 10, Atnola 12, Atnola 24, and Atnola 26. Four clones showed level of resistance better than the parent, namely Atnola 3, Atnola 5, Atnola 8, and Atnola 10. The result of field test showed that the seven clones produced better tuber than the parent Atlantic dan Granola, which were Atnola 5 dan Atnola 10 showed vigour, tuber weight, and better level of resistance, thus will be the candidate of high yielding cultivars.

Abstract

The objective of this research was to study shallot bulb formation on few concentrations of growth retardant succinic acid daminozid hydrazide (SAOH). Completely Randomized Design with 2 factors were used in this experiment. The first factor was four concentrations of SAOH (0, 30, 60 and 90 ppm) and second was two cultivars of shallot (Bima Juna and Kuning Tablet). The cultivars did not give significant effect to total number of leaf, shoot, root, number and weight of bulb, diameter of bulb, and height of plantlets. While SADH concentrations gave very significant effect to number of leaf, but not significant to number of root, number and weight of bulb, diameter of bulb and height of plantlets. Combinations of the two factors only gave significant effect to number of leaf and shoot but not significant to number of root, number and weight of bulb and height of plantlets.   Keywords: bulb formation, SAOH, shallot

Abstract

In supporting the replacement of potato varieties with the varieties that are adaptive to drought, effective and fast methods are needed. One of which is through in vitro screening of drought-tolerant genotypes. The aims of this research were to determine the appropriate concentration of sorbitol as a critical limit in the in vitro screening process of drought-tolerant genotypes, as well as to determine vegetative characteristics that could be used as indicators of in vitro selection and also to obtain in vitro drought-tolerant genotypes. To achieve these objectives, we used single-nodal explants of seven genotypes cultured for six weeks on MS media added with four levels of sorbitol concentration. Of the four treatments, sorbitol level that could distinguish susceptible and tolerant plants was 0.2 M sorbitol and at this concentration, the characteristics that showed significant interactions were plant height and root length, so that both characteristics could be used as selection indicators for the analysis of tolerance tests for the seven genotypes. The results of tolerance test using the analysis of relative decline and stress-susceptibility index (SSI) showed that PKHT4 and PKHT6 were the genotypes that were tolerant in vitro. Keywords: drought tolerant, in vitro, Solanum tuberosum, sorbitol
