Abstract

Paddy is one of the important cereal crops as food a main food for a third of the world's population, including Asia. Production of paddy rice plants can be improved through plant genetic improvement. The ebjective of this study was examine the genetic diversity, heritability, and correlation between the characteristics of several local upland rice cultivars. This study was carried out in Tamarenja Village, Sindue District, Donggala Regency, Central Sulawesi Province. It was began in May to October 2018. A Randomized Block Design with eight cultivars as a genotypic treatment and reapeted three times was used in this study. There were 24 trial plots in total. Variables observed included plant height, number of leaves, length of leaves, number of tillers, number of productive tillers, age of panicle exit, panicle length, harvest age, number of seeds per panicle, seed length, seed diameter, weight of 100 seeds, and total yield. The results showed that the genetic influences were more dominant than the environment on all observed variables except the weight of 100 seeds and seed diameter. The number of seeds per panicle, the number of tillers and the number of productive tillers were traits that have a high value on heritability and genetic progress. Panicle length, seed diameter and weight of 100 seeds were characteristics that have a high genetic correlation coefficient on upland rice yields. The weight of 100 seeds has a direct influence and high genetic correlation to the results so that it can be used as a direct selection criterion to increase upland rice yields.

Abstract

This study aims to determine the characteristics of mango plants relied on morphological and anatomical leaf of mango plants in the villages of Nambo and Laroue,subdistrict of East Bungku, Morowali district. An observation of morphological features was conducted in Nambo and Laroue, whereas anatomical observations had been made ​​in the laboratory of Biotechnology, Faculty of Mathematics and Natural Sciences, University Tadulako, from April to July in 2016. The morphological parameters observed includedage of the plant, plant height, stem diameter, canopy diameter, canopy shape and color bars. The alteration of leaf anatomy consists of the size of the stomata, the size of the epidermis, and stomatal index. Moreover, the resulthighlightsmorphological and anatomical characters observed on cluster analysis, described in the form of a dendrogram.The implication of the cluster analysis for two villages resultsin four accessions, namely NM1, NM2, NM15 and LR4 that can be benefited as the planting material of quality mango seeds which will be cultivated.
