ABSTRACTThe fruit of ornamental chili functioned as ornamental as well as for consumption, and therefore it requires diversity of traits for selection process. Information on inheritance pattern of the traits are needed for effective selection. The ideotype of ornamental chili are shortened internode that form a bouquet of flowers, erect fruit orientation and contain anthocyanins for attractive appearance. The research was aimed to study qualitative characters inheritance associated with shortened internode, fruit orientation and anthocyanins content. This study used 6 population including female parent (P1) which has anthocyanin in flower parts, the male parent (P2) bird pepper which has the character of a shortened internode, F1, F1R, BCP1, BCP2, and F2. Data were analyzed with Chi-square test to determine the Mendelian ratio in the F2 population. The results showed that there were characters that was controlled by one gene or two genes. Shortened internode and erect fruit orientation were controlled by a single recessive gene with a ratio of 1:3. On the other hand the color of anthocyanin in the anther stem was controlled by one dominant gene with a ratio of 3:1. The characters controlled by two genes that were dominant and recessive epistasis was the color of anthocyanins in the anther with the ratio 13:3.Keywords: Mendelian ratio, antosianin, shortened internode

The responses of cayenne pepper to salinity need to be elucidated for developing saline tolerant varieties. The study aimed to reveal the morphological and physiological responses of four cayenne pepper genotypes under salinity stress conditions. The research was conducted at the Tajur 2 experimental station of IPB University, Bogor, Indonesia, from October 2019 to March 2020. A two-factor randomized complete block design with five blocks as replications was used in this experiment. The first factor is the genotype of cayenne pepper (Sigantung, CR10, CSR1, and CRK1) and the second factor is salinity level (0-1, 2-4, 5-7, and 8-10 mS cm-1). The results indicated that the salinity significantly affected the morphological and physiological traits of cayenne pepper plants. Salinity 8-10 mS cm-1 on morphological traits caused the highest decrease in the number of flowers (74.65%), number of leaves (71.23%), fruit weight (58.48%), and root length (49.81%). In addition, a concentration of 8-10 mS cm-1 also caused the highest decrease in physiological traits. The highest effect of the treatment occurred in stomata conductance (29.37%), transpiration rate (26.47%), intercellular CO2 concentration (21.83%), and chlorophyll index (20.19%). Based on the average value of the stress sensitivity index (ISC), the Sigantung (1.2) and CSR1 (1.0) genotypes were categorized as salinity sensitive (ISC >1.0). On the other hand, CR10 and CRK1 had an average ISC value of 0.8, so they were categorized as the moderate tolerance to salinity (0.5<ISC<0.1). Keywords: stomatal conductance, intercellular CO2 concentration, stress sensitivity index, root length

The quality and quantity of nutmeg fruit, seed and mace can be improved through managing fruit and seed production. Fruit development was affected by climate, flower initiation and pollination process. This study aimed to determine the correlation between climate, position, distance of pollen donor to female nutmeg trees, and the ratio of female and male trees to nutmeg yield. The study was conducted at the nutmeg germplasm collection garden at Cicurug (550 m asl), Sukabumi, tested 295 nutmeg trees from 27 locations in Indonesia. Data production of female trees was based on 2005-2017 data. All nutmeg trees were mapped using the GPS Garmin 76c5x. Tree sex was determined by male or female flowers domination in each tree. Correlation of the climate factors and production was analyzed using Pearson Correlation. The distance, position and the proportion of female to male trees were evalated by t-test at 5% level. Ratio of female and male trees to produce high yield was 4 : 1. Rainfall (280-430 mm/month) and temperature (24 - 25o C) during the pollination period (8-7 months before harvesting) were positively correlated with production by 57.9 % and 82.3 %. The position and distance of pollen donors to female trees had no effect on production. However, the distance between pollen donors and female trees above 15 m produced an average production equal to 15 m. The number of trees around tree samples had no effect on nutmeg production, but light intensity at 61,425-88,480 lux absorbed by trees could enhance the yield. Nutmeg required sunlight to penetrate plant canopy in order to induce fruit production.
