Abstract

The aims of this research to evaluate and get a description of the important properties of some genotypes of cucumber to be used as a material in further breeding programs. The study was conducted at the experimental garden Indonesian Vegetables Research Institute, Lembang, 1,250 meters above sea level from June to August 2014. The research material using five genotypes of cucumber seed germplasm collections along with seven genotypes its segregan and 6 commercial varieties. Research using randomized block design (RAK). The results showed genotype LV 2904-2, LV2276-3, LV 2276-4, LV2902-1 and commercial 1 could potentially be developed further because it has the character according to the tastes of consumers. Genotypes with high yield potential generated by LV 2904-1, LV2276-3, LV 2276-6, LV2276-7 and commercial 1.   Keywords: Cucumber, genotype, phenotypic.

Abstract

ABSTRACT Yield Trial of Cucumber Hybrid Lines at Bandung, Garut, Sumedang on Dry season and Wet season. The experiment was a series of activities to numbers of location and seasion of field trial for variety released. The experimental design  was Randomized Complete Block Design with 4 replications and consisted of 40  plant per plot. The objective of the research was to find out high yielding of cucumber lines for Bandung, Garut, Sumedang at dry and wet season. The results obtained that Hybrid one washighest yielding (40.97 ton/ha) than check variety of Roberto (33.51 ton/ha). The cucumber of hybrid one were comparable to check variety of Misano (41.82 ton/ha) and Wulan (41.00 ton/ha). The cucumber Hybrid one were adapted at mid altitude of Districts Garut, Sumedang and Bandung.   Keywords : cucumis sativus , hybrid lines, yield, location,season

Abstract

The study was conducted at Indonesian Vegetable Research Institute in March to December  2009 with an  altitude of  1250 masl.  The  objective of study was  to determine the  effectiveness of  EMS  in  producing  carrots male  sterile.  The experiment was arranged in Complitely  Randomized  Block  Design  with  two factors  and three replication.  The results indicate  that the  local  carrot  cultivars have the survival to maturity better than hybrid varieties. The highest percentage of  living  plants  showed  by  carrot  cultivar  origin  Cipanas  (73.21%).  The percentage of live plants is affected by the EMS treatment only until the age of 60 HST.  Increased concentrations of EMS  resulted in  decreased  percentage of  live plants.  Increased concentrations of  EMS  also  tends to  reduce the weight of thousand grains carrot seed produced from the M1 generation. Visual appearance of  pollen  on  all  EMS  treated  the same as the  control, that is  pithy  and  bright yellow. Treatment of  various EMS  concentrations level  provided  the individual has not been effective in producing carrots male sterile. Key words: carrot, male sterile, EMS.

Abstract

This study aims to determine the effectiveness of arrangements between fermentation time and using NaOCl when washing the tomato seeds to improving the physical quality of the seed without decreasing seed viability. The experiment was conducted in May 2011 at the Laboratory of Seed Technology, Vegetable Crops Research Institute, Lembang. Research using tomato strain 6046 CLN physiologically ripe. Each treatment consisted of 25 grains of seed and repeated 4 times. The experiments were performed using analysis of completely randomized design (RAL). The results showed that the longer the time needed for fermentation, the pulp will be more easily separated from the seed. Washing using bayclin solution can improve the physical properties of tomato seed so that the color becomes brighter without causing a decrease in viability and vigor. Keywords: Fermentation, tomato, viability, vigor.

Abstract

Post-harvest loss is an obstacle for tomato farmers that cause tomato farming being unprofitable. Utilization of mutant genes prolong tomato fruit shelf life through crossing is one of the best solutions to improve the fruit quality. The objective of this study was to determine the success of cross-pollination between commercial tomato varieties and shelf life of mutant tomatoes. Two mutant tomato lines Sletr1-1 and Sletr1-2, and one wild type strain were crossed with four commercial varieties (Intan, Mutiara, Ratna, and Mirah ). The results showed that the success rate of crossing ranged from 77.50% to 100%, with an average of 95.76%. The average maximum growth potential of seeds produced was 89.17% with the lowest value of 75% and the highest 98.5%. The most top success of crosses was built by a combination of crossing Ratna x Sletr1-2, and the combination of Mirah x Sletr1-1 showed the lowest percentage of the crossing. The Intan showed the highest success as female parent of crossing, while Mirah was the lowest production of the crossing. The plant height of all hybrid was smaller compared to the commercial varieties.

Abstract

Tomato varieties cultivated in Indonesia is still susceptible to late blight. This research aims to determine the level of resistance of some strains of tomato to late blight. The research was conducted at the field trial Indonesian Vegetable Research Institute Lembang located at an altitude of ± 1250 above sea level. The type of soil Andisol temperate type B, with a daily average temperature ranging between  19-24  °  C,  relative  humidity  ranged  between  34-90%  and  an  average rainfall  of  2207.5  mm/year.  The  research  was  conducted  from  March  to  May 2015.  The  studies  used  randomized  complete  block  design  (RCBD)  with  16 treatment  lines/varieties  consisting  of  15  strains  of  balitsa  tomato  germplasm collection and the commercial varieties called "Intrend" as a control. The results showed that there are seven strains that have the same relative level of resistance to  the  control  varieties  of  the  intensity  of  late  blight  caused  by  the  fungus Phytophthora infestans (Mont.) De Bary, the strains are 1602-14, 1608-14, 1611-14,  1616-14, 1618-14,  1620-14, and  1621-14. Furthermore,  these  strains can  be used in further studies to obtain varieties resistant to late blight.Keywords: Late blight, line, tomato, variety.
