CHARACTERIZATION AND EVALUATION OF APPEARANCE RICE (Oryza sativa L.) LOCAL EAST TIMOR AND RICE INDONESIA

Abstract

Rice is an important commodity for the majority of the population, especially in the continent of Asia use rice as a staple food. The state of Indonesia and East Timor, rice as the main food source that needs continue to increase because in addition to the population continues to grow at a rate of increase of about 2% per year, as well as the change in consumption pattern of the population of non-rice to the rice. Interest characterization and evaluation of the appearance of rice(Oryza Sativa L.) locally Timor Leste and Indonesian rice are getting Local rice genotypes Timorese suitable for cultivated in paddy fields. This research using a randomized block design (RBD) consisted of 9 treatments and 3 replications. The materials used are high-yielding rice varieties namely IR-3 64, Ciherang, Cimelati and 6 local rice genotypes Timor Leste, namely Hare Foam, Fafulu Hare, Hare Bauk Morin, Mean Hare, Hare and Hare Modok Fulan. Results showed that the highest plant length at the age of 10 MST contained in the local rice Hare Bauk Morin(134.67 cm), Number of tillers(40.30) the number of leaves(4.64).Flowering date and time of harvest shortest genotypes present in Morin namely Hare Bauk flowering date (39 days) and time of harvest (105 days). The highest number of panicles contained in Hare Mean genotype, high-yielding varieties IR64, Ciherang and Cimelati. The length of the longest panicle genotypes present in Foam Hare, Hare Hare Fafulu, and Fulan. The number of filled grains per panicle most contained in superior varieties IR64, Ciherang and Cimelati. The highest weight of 1000 grains contained in Cimelati varieties (vu3) with Hare Bauk Morin, IR64 and Cherang varieties. The highest rice yield for local rice genotypes present in Hare Bauk Morin (G3) of 9.79 ton.Ha-1 while yielding varieties there exist varieties Cherang (vu2) of 9.74 ton.Ha-1.

Agronomics, Genomics, Breeding and Intensive Cultivation of Ciherang Rice Variety

“…Introgression of AG1 QTL from donor parent Kho Hlan On and AG2 QTL from donor parent Ma-Zhan Red and recipient parents PSB Rc82 and Ciherang-Sub1 potentially enhance the germination and seedling growth under flooding condition. Elite rice lines which carrying AG1 and AG2 QTLs showed less lipid peroxidation, higher á-amylase activity that increase the Source: (Baptista et al, 2018;Arief et al, 2018;Asbur, 2013.;Astuti et al, 2013;Biswas et al, 2021;Fitriah et al, 2019;Hazmi et al, 2019;Helina et al, 2018;Ibrahim et al, 2021;Isnawan et al, 2020;Juradi et al, 2017;Kinose et al, 2020;Liang et al, 2021;Nuraeni et al, 2014;Paiman et al, 2021;Rahmawati et al, 2021;Santosa and Suryanto, 2015;Shresta et al, 2018;Susiyanti et al, 2020;Widiasri et al, 2022) starch degradation and improve ascorbate, soluble sugars, and total phenolic content which leading to the higher germination and seedling growth under flooding condition.…”

“…Rice field areas in Indonesia are reaching 13.84 million ha with a total rice production up to 71.28 million ton and with an average rice yield 5.15 ton/ha (Indonesia Central Body Statistics Data, 2013). Ciherang rice variety known as superior and high-yielding variety originating from Indonesia that release in year 2000 and cultivate widely in Indonesia with the grain yield almost 10 ton/ha (Baptista et al, 2018). Ciherang was developed at the International Rice Research Institute (IRRI), Philippines (IRRI, 2015;Arief et al, 2018) by multiple variety crosses, including IR-64 as the background parent.…”
