The implementation of community service activities in Surau Village involves the academic community including lecturers and postgraduate students. This implementation was carried out in the form of lectures and discussions between the service team and Surau village residents. This community service is related to the welfare and food security of residents in Surau village which needs to be improved. Counseling and practice of planting sweet potatoes in sacks was carried out jointly between the service team with the participation of mothers from Surau Village. Surau village residents are enthusiastic and enthusiastic about participating in community service development activities carried out by lecturers and postgraduate students from the Agroecotechnology Masters Study Program. In this activity the service team brought sacks containing planting media and sweet potato seeds. The sack containing the planting medium is perforated at several points which represent the distance between the plants when planted in the raised bed. In addition to having holes prepared at points for planting sweet potato stems, the sacks are also provided with holes in which mineral water bottles have been installed and holes have been prepared to drain the water if conditions are not rainy. In practice, planting sweet potato stems is very easy and fun and when the sweet potatoes start to grow they can be used as ornamental plants in the yards of the residents of Surau Village.

The breeding of upland rice with New Plant Type characters in relatively short time can be done by using anther culture technique. The technique has been recognized as a rapid and efficient technology for crop improvement. Plant materials used in this research were F1 crossing P1 (Fatmawati x Way Rarem), P2 (Fatmawati x SGJT-28), P3 (Fatmawati x SGJT-36), P4 (Way Rarem x Fatmawati), P5 (SGJT-28 x Fatmawati), and P6 (SGJT-36 x Fatmawati). Media for calli induction (N6) and regeneration (MS) were according to Dewi methods (2003). The results of this study indicated that P3 (Fatmawati x SGJT-36) and P6 (SGJT-36 x Fatmawati) from resiprocal crosses gave better response in anther culture than the others crosses for their calli induction and green plant regeneration. From the six F1 crosses, 348 (53.5%) spontaneous doubled haploid (DH) pure lines were obtained, six lines from Farmawati x Way Rarem, 13 lines from Fatmawati x SGJT-28, 187 lines from Fatmawati x SGJT-36, three lines from Way Rarem x Fatmawati, five lines from SGJT-28 x Fatmawati, and 134 lines from SGJT-36 x Fatmawati. These lines should be evaluated and characterized for their agronomical and morphological traits. Key words: Anther culture, doubled haploid, callus induction, green plant regeneration

The development of new plant type of upland rice in relatively short time can be done by using anther culture technique. The technique has been recognized as a rapid and efficient technology for plant improvement. Plant materials used in this research were 320 s doubled haploid lines derived from anther culture and their 4 parents namely Fatmawati, SGJT-28, SGJT-36 and Way Rarem. Observation was conducted on plant height, number of productive tillers, days of flowering and maturity, length of panicle, number of grains per panicle, number of filled grains per panicle, percentage of unfilled grains, weight of 1000 grains and weight of grains per hill. The result showed that there were broad variations in the agronomic characters of doubled haploid lines. There were 58 upland rice lines can be obtained with new plant type characters (NPT). Several lines showed superior characters. Line P6-105, P3-134, P3-135, P3-175 had productive tiller more than that of parental, P3-160, P3-196, P6-274 had long panicle, number of grain per panicle and low percentage of unfilled grain, P3-135, P6-271, P6-274, and P6-276 had weight of grains per hill. These lines had potential as new plant type of upland rice. Length of panicle, number of grains per panicle, number of filled grains per panicle, and weight of grains per hill had high heritability and wide genetic variability. Key words: Genetic variability, doubled haploid, anther culture, upland rice

Anther culture is one of tissue culture methods which can be applied to plant breeding programs in order to accelerate the process of obtaining pure lines. The successful development of rice varieties is highly dependent on genetic diversity and desirable traits. To obtain the genetic variability of doubled haploid lines through anther culture techniques, anther F1 or F2 were used as explants sources. The objectives of the study were to select and characterize doubled haploid lines of upland rice having the characters of new plant type, and to study the genetic variability and agronomic characters of tested doubled haploid lines. A total of 58 doubled haploid lines, and four parental lines i.e. Fatmawati, SGJT-28, SGJT-36, and Way Rarem were used in this study. The experiment used completely randomized design with three replications. Results showed that the characters of the doubled haploid lines vary considerably. Selection of the character i.e. number of productive tillers, number of fi lled grain per panicle, and percentage of empty grain was more effective to be selected because they were well correlated to weight of grain per hill, possessed high heritability values, and have wide genetic variability. Based on productive tillers number, number of fi lled grains per panicle, fertility, weight of 1,000 grains, and weight of grains per hill, the lines of P3-26, P3-27, P3-28, P4-45, P5-50, P6-103, P6-105, P3-120, P3-134, P3-135, P3-150, P3-158, P3-248, P3-249, P6-271, P6-272, P6-274, P6-276, and P6-295 were potential for further selection for new type of upland rice.
