Abstract

Microsatellite markers or simple sequences repeats are DNA - based molecular techniques that areused to see the different among accessions and inbred lines. There are three methods to analysis the results ofthe polymerase chain reaction of microsatellite markers namely polyacrylamide gel electrophoresis (PAGE),capillary electroforesis, and Metaphor Agarose Gel Electroforesis (MAGE), and the Use of MAGE assessedmore easily and economically the polymorphic pattern of DNA markers. This study aimed to obtain fast,effective and efficient in term of easy and cheap technique to identify microsatellite markers of some blackrice cultivars and F2 populations from crosses between black with white rice. The results showed that MAGEsuccessfully separated clearly SSRs alleles with different sizes of less than 25 bp .

Abstract

Purple tomato is the only cultivated tomato containing anthocyanin inside the fruit, while multi-pistil tomato has a unique shape and the ability to be split into smaller parts without damaging the whole fruit. Purple tomato breeding is a new direction of agriculture research to enrich antioxidant fruit, which nowadays is increasingly in demand. The objective of this research was to obtain multi-pistil tomato fruit containing anthocyanin (purple colored), also to discover the inheritance patterns and heritability of qualitative traits related to fruit color and shape obtained from multi-pistil and purple tomato crossing. This research was conducted using seven populations consisted of 2 parental populations (Multi-pistil Tomato and Purple Tomato), 2 first progeny populations (F1 and F1 Reciprocal), 2 backcross populations (BC1.1 and BC1.2), and second progeny population (F2). The result showed that pistil type, unripe fruit color, ripe fruit color, fruit shape and fruit type were inherited autosomally. The inheritance pattern of the traits followed the epistasis gene interaction with moderate to high heritability value.

Abstract

The objective of this research was to determine the diversity and relationship of sapodilla accession derived from districts in DIY based on DNA profiles. From the screening of 20 total primers, five primers (OPA 20, OPB 5, OPB 6, OPB 8, and OPC 19) producing polymorphic bands in RAPD analysis were selected. Different-shaped samples of sapodilla randomly collected from Bantul, Gunungkidul, Kulonprogo, Sleman and Yogyakarta city were used in this research. The analysis of molecular data was performed by using NTSys pc-2.02 and GenAlex 6.1 program. The clustering indicated that the accessions tend to group by their locations. However, there was no corelation between DNA marker and the fruit shape. The first group comprised samples from Yogyakarta city (Keraton Yogyakarta), Bantul and Kulonprogo while the second group consisted of samples from Sleman and Gunungkidul with genetic similarity of 53% and 37% respectively. The genetic diversity was high (PLP = 98.85% of 87 loci and H=0.280±0.14) comprising the genetic diversity within population (53%) which was greater than genetic diversity between populations (47%). Having the highest genetic diversity, Gunungkidul should be potential for conservation and selection of sapodilla in DIY.
