Early Yield Testing and Selection of Upland Rice on Observational Study in Kebumen, Central Java

The use of upland rice variety is an effort to expand rice cultivation to dry land due to the decreasing of fertile land in Indonesia. To develop a high yielding rice line, a primary population with high genetic diversity is needed in character related to grain yield. This experiment aimed to study the genetic variability of some important characters of upland rice lines as primary data for the selected program. The research was carried out in the farmland of Mirit Village, Kebumen, Central Java. The genetic material consisted of 203 new promising lines and five varieties as a check, namely Inpago 6, Inpago 8, Limboto, Situpatenggang, and Situbagendit. This observation yield trial used an augmented design with five replicates of the check varieties, with a spacing of 30 x 15 cm. The data analysis showed that the rice lines, line vs. check, and block were significantly different in the number of productive tillers. The significant effects of lines with the check varieties were in plant height, flowering age, harvest age, and a number of productive tillers. The number of productive tillers had wide genetic variation, broad-sense heritability, and high genetic gain so that it can be utilized as selection criteria. Twelve lines were identified as a higher number of productive tillers, and three lines had a higher yield compared to the best varieties of Situbagendit.

Phenotypic appearance the yield character of five genotypes of cayenne pepper at Sukamantri, Ciamis

The purpose of this experiment is to evaluate the phenotypic appearance the yield character of five genotypes of cayenne pepper at Sukamantri, Ciamis region. The experiment used a randomized block design, with five replications. The experiment material consists of five genotypes of cayenne pepper, namely Unpad Ratuni, CR8873, Dewata, Taruna, and Rabani. The experiment was conducted at Sukamantri, Ciamis with altitude of 983 m above sea level (asl.) from August 2017 to February 2018. Data observed included fruit length, fruit diameter, fruit weight per fruit, fruit weight per plant, fruit weight per plot, and fruit weight per hectare. The experiment results show that there are differences in phenotypic characters among the five genotypes tested. Genotypes of the Gods, CR8873, and Ratuni Unpad show the highest potential yield (10.961 ton/ha, 0.345, and 10.232), with fruit weight of fruit per 1.382 gram, 0.911 grams, and 1.311 grams.Keywords: cayenne pepper, phenotypic character, yield
