Abstract

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

Abstract

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.

Abstract

Sweet corn is a result of recessive mutation which occurs naturally in gene that controls the conversion of sugar into starch in corn seed endosperm. There are 3 main genes that affect corn sweetness, namely sugary gene (su), sugary enhancer gene (se), and shrunken gene (sh2). This study aims to obtain a general combining ability value for the sweet corn lines, which will be the parent in diallel crosses; obtain the information of general combining ability, specific combining ability, and heterosis value for sweet corn lines; and obtain one or more promising single cross hybrids that will be potential for high yield and resistance to downy mildew disease. The study was conducted from April 2009 until November 2011 at the Experimental Field Centre for Cereal Plant Study (BALITSEREAL), Maros, South Sulawesi. The results showed that five genotypes had moderately high yield: Mr4/SC/BC4-3-1B, Mr14/SC/BC4-6-1B, Mr11/SC/BC4-3-1B, Mr14/SC/BC3-8-1B, and Mr12/SC/BC4-6-1B. The attack level of downy mildew that was classified as resistant has 0 to 7% rate. The combination of crosses that produce better productivity than all the varieties are: C × A (Mr11/SC/BC4-2-1B-1 × Mr12/SC/BC4-5-B-1), A × D (Mr12/SC/BC4-5-B-1 × Mr11/SC/BC4-2-1B-1), E × B (Mr12/SC/BC3-3-1B -1 × Mr14/SC/BC4-6-1B-1), and B × D (Mr11/SC/BC4-2-1B-1 × Mr14/SC/BC4-6-1B-1 ). Five hybrids can be continued for the preliminary testing of yields. Twelve candidate varieties do not have yield different than the checked varieties, so it can proceed to a multilocation trials to explore the advantages that can be released as new varieties.

Abstract

 The objectives of this study were to compare nonparametric stability measures, and to identify promising high yield and stability of chili pepper (Capsicum annuum L.) genotypes in eight environments. In every environment, a Randomized Complete Block Design was used with three replications. The method of Nassar and Huehn, Kang, Fox, and Thennarasu was used to analyze the stability and high yield. Spearman’s correlation and Principal Component analysis distinguishes the methods based on two different concepts of stability: the static (biological) and dynamic (agronomic) concepts. The top method was found to be the dynamic stability. Meanwhile, the methods of Si1, Si2, Si3, Si6, Npi1, NPi2, NPi3 and NPi4 were found to be the static stability. Based on the ranking frequency stability of the nonparametric method, the genotypes with the highest frequency of static stability ranking were genotypes IPB002003, IPB002046, IPB009019 and Tit Super, whereas IPB009002 and Tombak were categorized as those of dynamic stability. Genotype IPB120005 and IPB019015 were less adaptable in the multiple environments tested. It shows that the genotypes were specific in certain environments. IPB120005 had high yield and specific location in Boyolali in dry season and IPB019015 genotype was specific in Bogor in wet season. Keywords: chili pepper, nonparametric stability, high yield, dynamic stablility

Abstract

Inheritance of resistance trait to ChiVMV was studied in intraspecific capsicum population derived from a cross between two Capsicum annuum line, PBC495 as a resistance line and ICPN12#4 as a susceptible line. The resistance was assessed by diseased index (DI) and score of absorbance value at  405 nm, two weeks after inoculation. Based on t-test of F1 and F1R, it was concluded that there was no maternal effect. Nil symptoms resembling the resistant parent were identified in the progeny F2, BC1P1 (BC1 to the resistant parent) and BC1P2 (BC1 to the susceptible parent) populations. Segregation of resistance (nil DI and lower absorbance value) and susceptibility in the F2 fitted a 3:1 Mendelian ratio, indicating that resistance were controlled by a single dominant nuclear gene. Nil segregation of the trait in the test crosses in BC1P1 and a 1:1 ratio segregation in BC1P2 also confirmed the 3:1 gene segregating model as found in the F2. Heritability values of the trait were medium to high.Key words : inheritance, resistance, ChiVMV, pepper
