An experiment consists of two separated trial sets had been carried out at Probolinggo, East Java to study of manual thinning on berry cluster of "BS-6" grape by berry removal and cluster tipping. Berry thinning severities that were investigated consists of berry-removing and cluster tipping, each applied control, 20%, 40% and 60% thinning treatments at 7 or 14 days after anthesis. Berry removal did not influence to berry density but increased large-berry proportion and juice quality; since cluster tipping increased berry density, berry size and berry uniformity. Manual thinning at 7 days after anthesis gave better effect than at 14 days after anthesis

The objective of the experiment was to investigate the physical and chemical characteristics of three stadia of maturity based on a range of peel color from green to yellow or based on percentage of the yellow area of fruit peel (stadium 1 = 25-49 % yellow, stadium 2 = 50-74 % yellow, and stadium 3 = above 75 % yellow) on six genotypes of papaya. Each genotype exhibited different days to maturity for each stadium. The fruits of stadium 1, 2 and 3 for IPB 1 were picked at 130, 135, and 140 days after anthesis (DAA); IPB 10A at 160, 165, and 170 DAA; IPB 1 x PB 174 at 135, 140 and 145 DAA; while PB 174, IPB 1 x IPB 10A and IPB 10A x PB 174 were picked at 140, 145 and 150 DAA, respectively. The results indicated that peel firmness was affected by maturity stage on female fruit of IPB 10A. Maturity stage affected chemical characteristics of papaya included total soluble solids (TSS) content (IPB 10A, female fruit of PB 174, female fruit of IPB 1 x IPB 10A, and female fruit of IPB 1 x PB 174), vitamin C content (hermaphrodite fruit of 10 A, female fruit of IPB 1 x IPB 10A) and juice pH (hermaphrodite fruit of IPB 1). IPB 1 genotype can be harvested at all stadia of maturity stage. Hermaphrodite and female fruit of IPB 10 A, female fruit of PB 174, female fruit of IPB 1 x IPB 10A and female fruit of IPB 1 x PB 174 genotype would be better harvested at stadium 3 of maturity stage. Keywords: Carica papaya, papaya genotype, hermaphrodite fruit, female fruit, fruit quality, fruit maturity stage

Analisis Kedekatan Hubungan antar Genotipe Pepaya Berdasarkan Karakter Morfologi dan Buah Ketty Suketi; Roedhy Poerwanto; Sriani Sujiprihati; , Sobir; Winarso D. Widodo

A study was conducted to determine the variation and relationships among papaya genotypes based on morphological and fruit characteristics in order to produce high quality papaya fruits. Fruit characterization study is very useful for genotype improvement and genotype classiﬁ cation of papaya. In this study the morphological characters of 36 genotypes were analyzed to determine their phenotypic variabilities. The relationships between genotypes based on all of the morphological and fruit characteristics were tested by subjecting the data to multivariate principal component analysis and to cluster analysis. Based on the dendrogram generated from vegetative and generative characters, the 36 genotypes could be grouped into 11 clusters on a threshold of 1.6 and formed 6 clusters on a threshold of 1.8. The dendrogram was able to explain the close relationship between IPB 5 x IPB 1 and IPB 5 x IPB 4, IPB 2 and IPB 7, IPB 1 and IPB 3 genotype. The scattered diagram of generative variable divided the papaya genotypes into three groups based on fruit sizes i.e small group (IPB 1, IPB 3, IPB 4, IPB 3 x IPB 4, IPB 1 x IPB 9), medium group (IPB 5, IPB 7, IPB 8, IPB 9) and big group (IPB 2, IPB 10). The IPB 1, IPB 3 and IPB 4 were different from IPB 2 in fruit shapes, petal length of male ﬂ owers, inﬂ orescence size and fruit length. The hybrid plants obtained from crossings with IPB 10 were different from the other genotypes in the colours of female-, hermaphrodite-, and male ﬂ ower-lobes. Subsequently the scatter diagrams also revealed that several genotypes i.e. IPB 2 x IPB 6, IPB 1 x IPB 5, IPB 1 x IPB 9, IPB 5 x IPB 1 and IPB 5 x IPB 2 had superior characters ideotype similar to IPB 1, IPB 3 and IPB 8 genotypes. Keywords: Carica papaya, hermaphrodite, female, dendrogram, scatter diagram, ideotype

The purpose of the research was to examine the pollen germination process and growth rate of pollen tubes of papaya. Pollen tube growth of nine genotypes of papaya (IPB 1, IPB 2, IPB 3, IPB 4, IPB 5, IPB 7, IPB 8, IPB 9, and IPB 10) was investigated in this experiment in order to study their pollen germination rate and pollen viability. The fresh pollen were excised from the fl owers of papaya grown at Tajur Field Station of Research Center for Tropical Fruit, Bogor Agricultural University (IPB), Bogor. The extracted pollen was cultured aseptically on the Brewbaker and Kwack medium (pH 7.3) at ambient temperature of 26-28 °C. Pollen germination and pollen tube growth was observed under optical microscope with 100 and 400 magnifi cation. Papaya pollen viability was not associated with size-based categories of papaya fruits. IPB 4 had the longest pollen tube at fi rst 30 minutes after germination (115.5 µm), whereas IPB 10 had the shortest (99.5 µm). The distance from stigma to ovary in hermaphrodite fl owers varies with genotypes, ranging from 7.38 to 13.44 mm. Average length of pollen tube within four hours of germination for small papaya fruit category (IPB 1, IPB 3, and IPB 4) was 1,030.67 ± 19.14 μm, while the distance between stigma and ovary was short (14.85 ± 2.19 mm) so that the expected of fertilization process occurred sooner. At the end of the experiment (four hours after germination), IPB 1 genotype had the longest pollen tube (1,052 µm) while IPB 9 genotype (913 µm) had the shortest pollen tube. Genotype with the highest percentage of germination at the end experiment was IPB 2 (65.65%), whereas the lowest was IPB 7 (42.56%).
