“…According to Mustafa et al (2017), the cracking resistance measured by the fruit cracking index in tomatoes is controlled by two double recessive epistatic genes. Romadhon et al (2018) reported that the percentage weight of cracking fruit and fruit cracking index was inherited with a high heritability value.…”

“…In previous studies, ten of the best M7 mutant lines were resulted from induced mutations and selected for yield improvement and adaptation to the lowlands. Romadhon et al (2018) reported that these mutant lines have better yield potential than the parents. Descriptors of quantitative characters, both morphological and agronomic, do not always provide genetic differences or similarities between genotypes because quantitative characters are influenced by environmental factors (Kwon 2009).…”

Abstract. Arrufitasari PN, Sutjahjo SH, Wirnas D. 2022. Performance of tomato M7 mutant lines and their similarities to the parents based on SSR markers. Biodiversitas 23: 1239-1245. Tomato cultivation in the lowlands can be an alternative to increase tomato production so that high-yielding and lowland adaptive varieties are required. This study was aiming at determining the performance of M7 mutant lines and their similarities to the parents based on SSR markers. The experiments were conducted at KP Leuwikopo (250 m asl) and Plant Molecular Biology Laboratory, IPB University, Indonesia. The results showed that the G4 line had the highest productivity among the tested genotypes (36.72 ton ha-1) and significantly differed from all check varieties. The highest number of fruit per plant was 51.67 in the G7 line. On the other hand, G2, G3, G7, G8, and G10 lines had the lowest percentage weight and the number of fruits cracking and were not significantly different from the check varieties (Tora and Mawar). A total of 7 SSR primers detected 87 alleles with a range of 7-15 alleles per locus. The similarity between mutant lines and their parents ranged from 44-69%. The mutant most closely resembled the parent was the G3 line, while the most different based on molecular markers was the G9 line.

“…The plant samples were chosen for their superior criteria compared to control, namely the age of flowering and early age of harvest and has a high yield. According to Romadhon et al (2018) genotypes with earlier flowering time will usually be able to be harvested faster. Early maturing plants are very attractive to farmers and usually the plants that flower faster will bear fruit faster.…”

<a name="_Hlk39513249"></a>Raja Bulu is one of the banana varieties favored by the community because of its thick fruit flesh and sweet taste. However, its parthenocarpic characteristic and vegetative propagation make this banana variety has limited genetic variation. Attempt to improve the genetic variation was conducted through induced mutation breeding using gamma-ray mutagens. This research aimed to select M1V1 generation of Raja Bulu banana (Musa paradisiaca Linn.) obtained by gamma rays’ irradiation for their growth traits which are expected to produce banana varieties that have an early maturity and high yield. This study used a randomized complete block design without replication by observing the generative growth of each individual of Raja Bulu banana irradiated by gamma rays and without radiation as a control. The results showed that gamma-ray irradiation treatment caused Raja Bulu banana to be harvested earlier and produced higher fruit weight than controls. The gamma-ray irradiation had a random influence on Raja Bulu bananas. The 10 Gy gamma-ray irradiation dosage influenced the morphological diversity in the generative phase of Raja Bulu banana. The treatment of gamma irradiation resulted in 5 individual plants that flowered and matured earlier as compared to controls.

“…The tomato (Solanum lycopersicum L.) plant originates from American Southern and spread in several countries such as Chile, Ecuador, and Peru (Abiso et al, 2015). Tomato can grow and develop well in lowlands (0-200 m above sea level), medium (200-500 m above sea level), and highlands (500-700 m above sea level) (Romadhon et al, 2018). Tomato fruit is essential for making tomato sauce and paste, and can be consumed fresh.…”

Ethephon and calcium carbide are artificial ripening compounds that are often used to faster fruit ripening during postharvest. These two compounds were induced in non-ripening (NOR) tomato fruit line MA 131-6-3 because it produced endogenous ethylene and lower respiration. This study aimed to determine the effect of ethephon and calcium carbide on postharvest losses of NOR tomatoes for 14 and 28 days after treatment. Exogenous application of 1,500 ppm ethephon and 15 g kg-1 was given to NOR tomato fruit of line MA 131-6-3 and ambient conditions at temperature 28.08±1.80 °C and relative humidity 75.67±2.09%. This experiment was carried out in Sidoarum village, Godean district, Sleman regency, Special Region of Yogyakarta province, Indonesia, in 125 m above sea level. As a result, ethephon can increase fruit rotting. Furthermore, calcium carbide can accelerate metabolism which has an impact on physiological loss in weight, changing color to yellowish (b*), increasing vivid color (chroma), but the color of tomato fruit cannot turn red. Keywords: fruit ripening, fruit quality, postharvest, total soluble solids, total titratable acidity
