High yielding is one of main objectives on rice breeding. A preliminary yield trial is one of steps in the selection process of developing new varieties. Selection for yield and its component traits is a complex process due to the nature of quantitative traits. The right selection approach may improve the effectiveness of the selection. It is therefore the objective of the current study was to select high yielding rice genotypes. A total of 10 promising rice families were evaluated and compared to four check varieties. Least Significant Increase (LSI), and selection index (Mulamba & Mock and Genotype Ideotype Distance index) analysis were performed. LSI test showed that PP48-5 and SP101-3-1-5 had the best performance in almost all traits compared to the lowest average of the check variety. The selection index found that SP101-3-1-5 had highest yield selection index and was recognized as superior family by selection index. SP101-3-1-5 is selected as potential family to be developed as a new high yielding rice varieties

Downy mildew is one of the major diseases in maize that may decrease maize production in Indonesia. Downy mildew in maize is caused by Peronosclerospora spp. that are obligate parasites that cannot be grown in a synthetic growth medium. Efforts to control the disease by using resistant maize varieties and fungicides often did not give the expected results, this might be due to the variations of the pathogen that have diverse nature and responses. Identification and the understanding of the biodiversity of downy mildew are major key aspects in efforts to control the disease. The Identification of species morphologically is often difficult due to the limited distinguishing characteristics and close similarities between them. Molecular biology methods are now starting to be widely used because they can provide information about the diversity of an organism genetically quickly and accurately. Therefore molecular biology methods can be used to support the morphological observations. The use of molecular markers such as RAPD, RFLP, AFLP, and SSR as well as direct sequencing of specific DNA regions (rDNA, ITS region of rDNA and mtDNA) can represent the diversity of downy mildew. In Indonesia, generally, there are three main species that cause downy mildew in maize i.e, P. philippinensis, P. maydis and P. sorghi. In the future, the use of new molecular biology techniques may provide more information faster and accurately that may be able to open more possibilities for disease control efforts.

Red rice is known to have advantages, i.e. contain fiber and anthocyanin that have functional properties. The potential of red rice needs to be explored more intensively through various studies. One effort to develop brown rice as food is to process it into flour. In the process of flour processing, there are several steps that must be considered to get flour with good physicochemical properties, such as drying and grinding. The purpose of this research was to learn the effect of drying time and temperature on the physicochemical characteristics of red rice flour. Randomized Block Design factorial was used in this research. The treatment factors were drying time (A) and drying temperature (B). Factor A consisted of three levels i.e. 1 hour, 2 hours, and 3 hours, and factor B also consisted of three levels i.e. 50°C, 55°C, and 60°C. The parameters observed in this study were yield, bulk density, water holding capacity, swelling power, solubility, moisture content, and amylose content of red rice flour. The results showed that the drying times and temperatures significantly reduced yield, bulk density, and moisture content, but significantly increased water holding capacity, swelling power, solubility, and amylose content of red rice flour. The moisture content of red rice flour was in accordance with the standards (SNI 3549; 2009).

Plant-disturbing organisms such as pests, pathogens, and weeds cause problems in crop cultivation so they need proper handling. Soil solarization is an alternative to pest control. This paper discusses information on the control of disruptive organisms by solarizing technology. Some of the components that play a role in the solarization process, namely the sun as an energy source, plastic mulch as an energy source converter, and soil moisture as a trap and conductor of heat produced by plastic in deeper soil depths. Solarization of the soil is environmentally friendly and is carried out before planting by managing heat energy from solar radiation. The best soil solarization is by using transparent plastic sheets because they are translucent, where most of the light is transmitted through the plastic sheet and only a little is absorbed and reflected. High soil temperatures due to soil solarization can suppress soil pathogens, soil pests, and weed propagules and can increase soil fertility, growth, and crop yield.
