Abstract

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.

Abstract

Pigeon pea (Cajanus cajan) is potential as an alternative source of protein other than soybeans and is tolerant to dry conditions, but the cultivation of this plant has not been intensively carried out in Indonesia. This research aims to explore the characteristics of black pigeon pea and investigate the producing areas of black pigeon peas in Gunungkidul. Based on the field survey, 30 types of black pigeon peas were found. They were located in Pringapus and Klopoloro 1 Hamlets. This research was conducted on March-June 2018 in Yogyakarta. The observation variables in this study include research environmental condition and plant morphology, for examples, stems, leaves, flowers, pods and seeds. Morphological data were analyzed using NTSYS program. The results show that the height of pigeon pea plants ranged from 63 to 176 cm, the number of branches ranged from 18 to 35, the colors of stem were green to purple and the stem thickness was >13 mm. The similiarity of the coefficient value of pigeon peas in Pringapus ranged between 84% and 95%, while the similarity in Klopoloro 1 varied between 80% and 97%.

Abstract

Black rice generally has problems in cultivation such as relatively long plant life, high habitus and low productivity. Plant breeders use several methods in hybridization activities, such as backcross method that can lead to the development towards emphasizing the superiority of each parent. This research aimed to study and determined the success rate of the black rice lines F1 backcross and the parents’ performance. This research was conducted using F1 of promising lines, parental lines and the Jeliteng variety with 9 sets of crosses. Each line and variety were repeated 3 times, in total there were 57 experimental units. The observation parameters of this research were plant height, crossing success, weight of seeds, length and width of grain, flowering age, harvesting age also number of grains and unfilled spikelet. The results of this study showed that parents plant height was positively correlated with the number of productive tillers. The taller the plant, the more productive tillers and the more flowers can be crossed. The success of the cross can increase with the number of flowers crossed. The success of crosses between F1 black rice promising lines and their parents has a success rate range of 10.82% to 33.75%. The findings imply that F1 crossbreeding of black rice promising lines with their parents can be carried out to produce backcross offspring.
