Abstract

Drought-tolerant upland rice varieties are important to support increased rice production. These varieties must be resistant to biotic and abiotic stress and have high yield. Testing the potential of lines on dry, acid land to measure adaptability and yield. This study aims to determine the yield and determine the highest yielding line of F8 upland rice. This research was conducted from August 2022 to April 2023 in Air Rayak Village, Tanjungpandan District, Belitung Regency. This research was conducted using an experimental method with a randomized block design (RBD). The treatment consisted of 5 F8 lines consisting of 19I-06-09-23-03, 21B-57-21-21-23, 23F-04-10-18-18, 23A-56-20-07-20 and 23A -56-22-20-05 and 5 check varieties consisting of Inpago 8, Inpago 12, Rindang 1, Danau Gaung and PBM UBB 1. Data analysis used the Fisher test (ANOVA) followed by the LSI (Least Significant Increase) follow-up test. The results all lines and varieties tested were able to grow and produce in Belitung Ultisols. The yield of the F8 lines on ultisols in Belitung Regency ranged from 2.00-4.54 kg/plot. The F8 lines that had the highest yield was the 23A-56-20-07-20 line, which was 4.54 kg/plot (white rice paddy) and the 23A-56-22-20-05 line, which was 2.14 kg/plot (brown rice paddy).

Abstract

Breeding of corn plants resulting from crosses experienced problems with inbreeding depression. Inbreeding depression can cause a decrease of good characters in maize lines. Information about inbreeding depression needs to be known so that it does not appear in the maize lines. This research aims to determine the presence of inbreeding depression  in purple corn lines from open pollinated and to determine the morphological character as a selection criterion for the F4 lines. Research using experimental methods. Plant selection was carried out using the ear-to-row method. Isolation of plants using distance and time of planting method. Observation of morphological characters using Royal Horticultural Society (RHS) Color Charts and the inbreeding depression test. F4 lines has inbreeding depression on the characters of plant height, stem diameter, number of leaves, male flowering age, female flowering age, cob length, cob weight with husk, cob weight without husk, and weight of 100 seeds . The F4 lines of corn plants that did not experience inbreeding depression on plant height and stem diameter characters in lines F4-PxU-11-25-18 and F4-PxU-11-25-25. Characters that can be used in the selection of F5 generation corn lines are plant height, stem diameter, cob length, cob weight with husk, cob weight without husk, and weight of 100 seeds. These characters can be used as selection criteria for the next generation.

Abstract

The success of rice production is partly determined by the quality of the seeds used. The main challenge in maintaining seed quality is proper management to ensure that seeds remain preserved during storage. This study aims to evaluate the effect of storage methods on the quality of local Bangka rice seeds, as well as the chemical composition of the seeds after being stored for 8 months. The research period is from February to December 2024, conducted at the Seed Laboratory and Plant Breeding of the Bangka Belitung University. The study uses an experimental design of a Completely Randomized Design in a split-plot pattern. The first factor consists of 6 accessions of local Bangka rice (Mukot, Jawa, Ungu, Pulut Hitam, Balok Merah, and Mayang Hutan). The second factor consists of 7 storage media (cans, 40-micron plastic, 120-micron plastic, plastic sacks, plastic jars, seed trays, and panicles). Each treatment was repeated 4 times. The results show that the Balok Merah accession exhibited the best performance, supported by the highest maximum growth potential, germination rate, vigor index, uniformity of growth, and normal seedling dry weight, along with more consistent moisture content. The panicle storage medium showed the best results in maintaining seed quality during storage, supported by the highest maximum growth potential and germination rate. The best treatment combination was the storage with panicles of the Jawa accession, supported by germination rate and the highest maximum growth potential. Proximate analysis indicated that the highest moisture content, ash content, and protein levels were found in Balok Merah. The highest fat content was in the Pulut Hitam accession, while the highest carbohydrate content was in the Mukot accession. There was a strong positive correlation between maximum growth potential and germination rate.
