Abstract

True seed of shallot (TSS) from open pollination crossing are in the heterogenous as a result of the heterozygous parents. This condition gives the opportunity to obtain new selected accession through the genetic variations of their seedlings. Five TSS cultivars of Biru Lancor, Pancasona, Tuk-Tuk, Lokananta, Sanren were used as planting materials to be evaluated the growth and bulb yield performance for the selection of excellent shallot selected accessions in bulb production. The 300 seeds of each cultivar were planted in the field of Faculty of Agriculture, Universitas Gadjah Mada, Banguntapan, Bantul District, Yogyakarta (100 m above sea level). All seedlings were observed for the survival rate, plant growth, and development of bulb. The results showed that the seedlings of Sanren, Lokananta, Pancasona, Tuk-Tuk, and Biru Lancor could germinate with different survival rate of 88%, 87%, 80%, 67.3% and 48%, respectively. There was a significant difference in number of leaves that effected in developing a single bulb and multi-bulb. Prospective selected accessions with high yield in lowland areas was as follows: Biru Lancor 12 plants (4%), Pancasona 20 plants (6.7%), Sanren 146 plants (48.7%), and Lokananta 25 plants (8.3%). All of the selected bulbs will be planted again for further evaluation in excellent trait of bulb aggregation (bulbs multiplication).

Abstract

The research aimed to propagate tea plants by air layering in order to obtain new plants with shorter immature plants period (TBM), which is 1.5 years, by utilizing wasted branches from routine clean pruning activities in tea plantations. The research was conducted from August 2018 to January 2019 at tea plantation of PT. Pagilaran, Batang, Central Java. Experiment using single factor treatment was arranged in a Completely Randomized Design with three replications. The treatment was layering media, consisting of husk charcoal, moss, and cocopeat, which were applied on GMB 7 and GMB 9 clones. The results showed significant effects of the layering media on the levels of auxin and cytokinin in GMB 7. The highest levels were found in the husk charcoal and moss media. Analysis of sucrose, glucose and total sugar as well as the physiological analysis of the air layering roots showed no significant difference in the fresh weight, dry weight, volume, surface area, diameter, and length of the roots. Husk charcoal resulted in the highest success rate of the air layering in GMB 7, which was 100%. Meanwhile, GMB 9 showed significant difference only in the auxin levels. There was no significant effect of layering media on the analysis of sucrose, glucose and total sugar as well as on the physiological analysis of the air layering roots. Both husk charcoal and moss media resulted in the highest success rate of the air layering in GMB 9, which was 58.33%.
