Papaya plants are hermaphrodite, pistillate, or staminate. Sex inheritance in papaya is determined by a single gene locus with three alleles of M which is dominant for maleness, MH for hermaphrodites and m which is recessive for femaleness. Only fruits from hermaphrodite plants are marketed since they have the necessary commercial characteristics, i.e., they are pear-shaped and have thicker flesh and a smaller internal cavity. Increased papaya yield has been limited mainly by the ratio of female to hermaphrodite (1: 2) plants normally occurring in orchards. This ratio causes great losses to papaya producers. Identification of seedlings sex during nursery stage is of prime iportance. In order to obtain simple DNA markers to identify sex expression in papaya, five SCAR markers of 20-21 primers were utilized. Examination of these markers into 24 genotypes of papaya from 12 populations of different genetic background revealed that pair of primer PKBT-5 had successfully differentiated male and hermaphrodite plants from female plants. Hence, PKBT-5 pair of primer can be utilized as DNA marker for sex expression character identification in papayas. Key words: Papaya, sex expression, SCAR marker

The genus of Carica comprises 21 species, among them three species have been domesticated and cultivated. They are Carica papaya, Carica candamarcencis and Carica monoica. In Indonesia, two species have been cultivated viz. Carica papaya and Carica candamarcencis. In this study, four accessions of Carica papaya species and one accession of Carica candamarcencis species were analyzed using RAPD technique. We successfully amplified a total I of 40 fragments from these DNA genome by using 6 random primers with GC bases content:::: 60% of each primer. The number of fragments of each primer ranged from 5 to 8 averaged 6.7 fragments per primer. Out of total fragments, 90% showed as polymorphic ranged from 5 to 8 on average 6 fragments per primer. A dendogram based on the UPGMA- link method using Nei and Li similarity and Principal Component Analysis (PCA) plot separated the accessions into two main groups, the Carica papaya species on the one side and the Carica candamarcencis species on the other side. The result demonstrated that RAPD analysis was able to reveal genetic difference between Carica papaya and Carica candamarcencis species, as well as genetic diversity in Carica papaya species.

Resistance evaluation to blast disease (Pyricularia grisea) on 12 paddy genotypes was carried out in the green house by using spray inoculated method with race 033 and 041 of P. grisea , and SCAR (Sequence Characterized Amplified Region) marker by using Pib primer pairs. The results revealed that among 12 paddy genotypes were classified into six resistance groups. The first group comprised two genotypes (Jatiluhur and Asahan) having three resistance genes. The second group comprised two genotypes (Oryza malampuzhaensis and O. punctata) having two resistance genes against race 033 and 041. The third group had one resistance gene against race 033, comprised one genotype (Way Rarem). The fourth group comprised one genotype (Danau Tempe) having two resistance genes against 041 race and Pib. The fifth group comprised three genotypes (Kalimutu, Maninjau and Laut Tawar) having two resistance genes against race 033 and Pib. The sixth group comprised two genotypes (Kencana Bali and Cirata) having no resistance gene to blast race 033 and 041, and Pib. These results indicated that Pib gene did not confer resistance to race 033 and 041 of Pyricularia grisea. Resistance to race 033 and 041 might be controlled by different resistant gene.

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.

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.

The aim of this study was to investigate the effect of rootstock and shoot types on in vitro mangosteen micrografting.The experiment was arranged in completely randomized design (CRD) with two factors. The first factor was the rootstocktype, i.e. rooted planlet from the germination of quartered seed, and rooted planlet from the germination of undivided seeds.The second factor was the developmental phase of scion, i.e. dormant buds, and flush (had new leaf more than 2-4 mm). Theresults showed that rootstock derived from the germination of undivided seed had a higher success rate than other treatmentson all variables, except for number of new leaves. The use of flush as scion was better than dormant buds; flush resulted in ahigher percentage of successful micrograft and longer shoots. In vitro micrografting had a better growth rate than grafting at the same age. The results of anatomical observation conducted at four months after micrografting demonstrated that there was a good graft union, indicated by excellent fusion between rootstock and scion xylem tissues.Keywords: flush, in vitro, micrografting, rootstock, scion

ABSTRACTResistance to yellow virus (YV) is an important breeding trait in melon. However information regarding genetic inheritance pattern of the character are limited. This study aimed to provide information on genetic control for resistance to YV in melon caused by Tomato Yellow Leaf Curl Virus (TYLCV). Twenty genotypes from three major melon groups (dudaim, cantaloupe, and inodorous) were evaluated using controlled inoculation method. The results revealed that one line, MEV1 from the dudaim group, showed high resistance to YV; while other lines belong to cantaloupe and indororus indicated as highly susceptible lines. Screening of the F1 from crossing between resistant and susceptible parents resulted in resistant F1 after inoculation and planted in endemic location. Subsequently, evaluation on F2 population revealed a non-normal distribution for disease severity score, indicating that resistance to YV in melon was controlled by major genes. Chi-square (χ2) test resulted in 13:3 ratio and indicated that the resistance to YV was controlled by 2 genes pair with dominant and epistasis recessive actions.Keywords: dominant and epstasis recessive action, major gene, Bemicia tabaci, Begomovirus
