Public demand for cayenne pepper is high, so it is necessary to improve the quantitative characteristics of chilies, one of which is by selecting. This research aims to obtain information regarding the mean and interval values of several quantitative characters, inbreeding depression, heritability values, and selection progress from five generations resulting from crossing two cayenne pepper parents. The genetic material used consisted of two chili parents, namely the genotype IPB C321 (female parent), and IPB C290 (male parent) along with the results of crossing the two in the F2, F3, F4, and F5 generations with a total of 580 individual plants. The research results showed that based on the mean value between the F2 to F5 generations, there was an increase in the observed characters except at harvest age. The observed characters did not experience inbreeding depression. The heritability value in the narrow sense shows the high criteria for fruit length characters in the observed generation, fruit weight per plant and weight per fruit in the F2 generation, number of fruit per plant in the F2 and F3 generations, and fruit diameter in the F3 and F4 generations. Other generations have heritability values in the narrow sense of low and medium criteria. In general, the progress of selection for quantitative characters in the five chili generations studied showed a decline, although there were decreases and increases in the generations and characters observed.

Melon breeding for fruit quality improvement is important to produce new varieties that meet consumers’ demand. The aim of this study was to elucidate the fruit characteristics of melon at five different maturity stages, involving several genotypes belonging to two cultivar groups: reticulatus and inodorus. The experiments were conducted in three planting seasons: (1) January-March 2015 (13 genotypes), (2) December 2015-February 2016 (56 genotypes), (3) February-May 2016 (9 genotypes). These trials were conducted at the Tajur II experimental station of IPB, Bogor, and each trial was arranged in a single factor randomized complete block design with three blocks. Maturity stages was determined based on fruit rind color and net coverage, and their effects on fruit quality were studied using combined analyses over seasons. Maturity stage significantly affected the fruit length, fruit diameter, flesh thickness, fruit weight, and sugar content. The average weight of the fruits at maturity stage 4 (838.90 g) and 5 (931.79 g) was significantly greater than that of stage 1 (584.42 g). The sugar content increased from maturity stage 2 (5.51 oBrix) to 3 (6.13 oBrix) and to 5 (8.18 oBrix). Fruit weight significantly correlated with fruit length (r = 0.53), fruit diameter (r = 0.85), fruit rind thickness (r = 0.33), and flesh thickness (r = 0.63). Maturity stages affected the quality of melon fruits, and therefore the determination of appropriate harvesting criteria is important in melon cultivations.Keywords: cantalupensis, correlation, inodorus, fruit quality, skin colour

ABSTRACTSugarcane cultivars tolerant to drought stress are needed for specific location. In vitro selection can be used to obtain plants tolerant to drought stress through regeneration of callus in the culture medium. The purpose of this study was to obtain regenerants from irradiated callus on the stress medium. The experimental design was a completely randomized design with two factors. The first factor was the regeneration medium (RG) added with PEG 6000, i.e., 0%, 5%, 10% and 15%, while the second factor was the dose of gamma ray irradiation i.e. 0 krad, 5 and 10 krad, and 15 krad. There were 12 treatments, each treatment was repeated 18 times and each repetition was a culture bottles planted with three clums of callus 10 mm diameter. RG medium was the MS medium added with 0.5 mg L-1 BAP, Kinetin 0.1 mg L-1 and IBA 1.0 mg L-1. The higher the concentration of PEG, the less regenerants were produced. Regenerants could be generated from the selection medium PEG up to 15%. Several shoots still produced from callus irradiated with 10 krad. Selection medium with PEG up to 10% decreased the precentage of albino regenerants. The gamma ray irradiation dose and the concentration of PEG significanly affected the number of roots produced.Keywords: drought tolerant, in vitro, polyethylene glycol, plantlets, albino

Excessive use of inorganic fertilizers is suspected to be the cause of low productivity and poor bulb storability that reduced their use. Goat manure organic fertilizer (GMOF) can be an alternative in reducing the use of these inorganic fertilizers. The study was conducted in March to June 2019 in the shallot field at Sukorejo Village, Rejoso District, Nganjuk Regency, East Java. The research aims to determine the dose of inorganic fertilizer which can be reduced by adding goat manure to increase the growth and production of shallot bulbs. This experiment used 2 factors, namely manure consisting of 2 levels (0 and 10 tons ha-1) and inorganic fertilizer consisting of 5 levels (0, 25, 50, 75, and 100% inorganic fertilizer reference dose). The treatment was repeated 4 times so that there were 40 experimental plots with a size of 2 m x 4 m, using Super Philip variety. The addition of 10 tons ha-1 of GMOF to shallot cultivation in Nganjuk Regency could reduce the use of inorganic fertilizer to 50%. Keywords: goat manure, nutrient uptake, organic, Super Philip
