Abstract

The estimation of yield component genetic parameters is an important step towards plant breeding activities. This research aims to obtain information about yield components that can be used to increase yield of yardlong bean and accessions of yardlong bean for direct use or breeding materials. The research was conducted at Agrotechnology Innovation centre of Universitas Gadjah Mada, located in Kalitirto, Berbah, Sleman, Yogyakarta. The research materials consist of 29 accessions and 5 high yielding varieties as controls arranged in completely randomized design. Each accession was observed morphologically including days to 75% of flowering, days to first harvest, pod length, pod diameter, number of pods per cluster, number of pods per plant, number of seeds per pod, weight of 100 seeds, seed length, the diameter of seed, potential yield pods per hectare. Observed data were analyzed with ANOVA followed by the estimation of genetic parameters and principal component analysis. The results showed that almost all traits had a high heritability value, except seed length which had a moderate heritability value. Accessions 113, 134, 135, dan 137 could be considered as the promising candidates  based on the earliest days to first harvest and highest potential yield.

Abstract

Cosmos has the potential to be developed as an alternative vegetable. Less characterization and evaluation of cosmos become obstacles in the process of its development. Characterization is the process of observing and identifying the physical, biological, and chemical properties of plants that aim to determine the characteristics of a plant. The purpose of this research is to ind the characteristics of each accession of Cosmos spp. and get accession of Cosmos spp. which has the potential to be developed or used as varieties material assembly. The research was conducted at the AIC (Agrotechnology Innovation Center) of Universitas Gadjah Mada in March-July 2019. The planting material used for this study was the collection of seeds of PIAT UGM from the Special Region of Yogyakarta and Riau. Fifteen cosmos accessions came from DIY and the other 18 came from Riau. Thirty-three accessions have diverse characteristics especially lower colours that are divided into 7 groups of lower colours namely yellow, gold, light orange, orange, pink, purple, and white. Accession number 39 has a rare white colour lower

Abstract

Yardlong bean (Vigna Unguiculata subsp. Sesquipedalis) is very potential commodity to be developed in Indonesia and Rhizobium has played an important role to increase pod production through free nitrogen ixation. Bradyrhizobium is a species of Rhizobium that is commonly found in vigna. The purpose of this study was to determine the response of twenty accessions of yardlong beans to Bradyrhizobiuminoculation and determine effective accessions with Bradyrhizobium inoculation. This research was conducted at AIC-UGM from March to July 2019. The planting material was 20 accessions of yardlong beans from AIC-UGM collection using seed inoculation methods. The result after inoculation of Bradyrhizobium treatment showed that the innoculation enhances plant height, number of leaves, root volume, root area, root length, root fresh weight, root dry weight, pod fresh weight, number of pods, number of effective root nodules, amount of root nodules and accelerate the age of lowering and harvest age in most accessions. Considering its response to the Bradyrhizobium inoculation, accessions of yardlong bean that have the potential to be developed for superior varieties are FBKP 143, FBKP 146, FBKP 147, FBKP 150, FBKP 152, FBKP 161 and FBKP 162.

Abstract

Eggplant is one of the commodities that started to be favouritely consumed and had economics value. There were many factors that affect the growth and development process of plant. One of those many factors are the environment condition such as drought. This research aims to know the tolerance level of eggplant accessions to drought. Plants grew in two comparative conditions, normal and drought. Drought is given by using interval water application about every 7 days. Observations were carried out to growth and yield components and continue measuring the stress effect using drought sensitivity index. The results show that plants develop an adaptation mechanism to drought by reducing its growth and yield components to survive. The result of further test and drought sensitivity index show that half of accessions have good tolerance to drought. Acessons that had goof tolerance to drought were SLTE 2, SLTE 3, SLTE 5, SLTE 6, SLTE 8, SLTE 13, SLTE 15, SLTE 18, SLTE 42, and SLTE 44.acc

Abstract

Yardlong bean is one of the commodities with very high economic value. To obtain good quality pods, it requires the right cultivating techniques such as the use of stake model and the use of superior varieties. The objectives of this study were to investigate the effect of stake model and varieties on the quality of yardlong bean pods. This research was conducted on the Agrotechnology Innovation Center of Universitas Gadjah Mada at March-June 2019. This research was arranged in factorial treatment design with Randomized Complete Block Design (RCBD) using three blocks as replication. The irst factor is the stake model i.e. single, double, and triangle. The second factor is varieties included Parade Tavi, Pujangga, Katrina, Wulung, and Kaloka. The observed quantitative data were analyzed using analysis of variance (ANOVA), followed by Scott-Knott with the level of credibility at 5 %. The results showed that the use of the stake models on different varieties does not indicated a signiicant impact on the quality of produced pod.

Abstract

Indonesia is the center of yardlong bean cultivation, so that it has a wide genetic diversity. The Vegetable Genebank of Universitas Gadjah Mada has a large collection of yardlong bean germplasm. Therefore, it is necessary to characterize the germplasm collection to identify the specific characters of each accession. Morphological characterization of yardlong bean was carried out based on quantitative and qualitative traits. The yardlong bean accessions that were being observed in this research were FB-KP 277, FB-KP 431, FB-KP 688, FB-KP 689, FB-KP 690, and FB-KP 728.The result showed that FB-KP 728 had the highest yield potential. Meanwhile, the yardlong bean accession with the lowest yield potential was FB-KP 277. FB-KP 277 was the only yardlong bean accession that had the specific characteristics, they were twining growth type, pale green leaf color, ovate leaf shape, and brown-cream seed color.
