Evaluation of vigor and viability of mutated jute seeds.

Jute fiber has long been known and used as a raw material for packaging agricultural products and is now being developed to support various industries. Improving fiber quality is important in supporting the development use of jute fiber in various industries. The aim of the study was to determine the percentage of vigor and viability of jute seeds with various doses of gamma ray radiation to improve the quality of jute fiber through mutation breeding. The study used a two-factor completely randomized design. The first factor consisted of three jute accessions, namely Branca, Halmahera, and Roxa. The second factor consisted of 12 gamma radiation doses, namely 450 Gy, 500 Gy, 550 Gy, 600 Gy, 650 Gy, 700 Gy, 750 Gy, 800 Gy, 850 Gy, 900 Gy, 950 Gy and control (without mutation treatment). The results showed that there was a significant effect and interaction between accession and radiation dose on the vigor and viability of jute seeds. The dose of 950 Gy increased the germination and simultaneous growth of Branca (9.09 % and 10.40 %) and Halmahera (6.74% and 6.78%). Gamma ray radiation decreased the radicle and hypocotyl length in all accessions at all treatment doses, respectively between 22.79% - 63.54% and 12.91-68.45%, in addition there was an increase and decrease in radicle and hypocotyl dry weight in all accessions at each treatment dose. A dose of 950 Gy can be used as a radiation treatment to improve the quality of jute fiber of branca and Halmahera. [ABSTRACT FROM AUTHOR]
