| The objective of this work was to estimate genetic gains in physic nut (Jatropha curcas) using selection indexes and to establish the best selection strategy for the species. Direct and indirect selection was carried out using different selection indexes, totalizing 14 strategies. One hundred and seventy five families from the active germplasm bank of Embrapa Agroenergy, Brasília, Brazil, were analyzed in a randomized complete block design with two replicates. The evaluated traits were: grain yield; seeds per fruit; endosperm/seed ratio; seed weight, length, width, and thickness; branches per plant at 0.5, 1.0, and 1.5 m; plant height; stem diameter; canopy projection on rows and between lines; canopy volume; juvenility (days to the first flowering); and... |

| An understanding of seed germination ecology of weeds can assist in predicting their potential distribution and developing effective management strategies. Influence of environmental factors and seed size on germination and seedling emergence of Convolvulus arvensis (field bindweed) was studied in laboratory and greenhouse conditions. Germination occurred over a wide range of constant temperatures, between 15 and 40 ºC, with optimum germination between 20 and 25 ºC. Time to start germination, time to 50% germination and mean germination time increased while germination percentage and germination index decreased with an increase in temperature from 20 ºC, salinity and osmotic stress. However, germination was tolerant to low salt (25 mM) or osmotic stress... |

| Abstract Rocoto pepper (C. pubescens), is one of the domesticated species of the genus Capsicum in South America. Currently, its supply and demand are arising in national and global market. The aim of this study was to determine the optimal extraction timing of the seeds of C. pubescens according to physiological and physical seed qualities. Seed qualities measurement include seed weight, number of seeds per fruit, total emergence, emergence rate, mean emergence time, mean daily emergence, survival percentage, peak value and emergence value. Treatments were evaluated for comparison as follows: seed extraction ranged from 0 to 3 days after harvest (T1), and seed extraction ranged from 14 to 17 days after harvest (T2). T1 presented seeds with the best... |

| During 1995/96 and 1996/97, experiments were carried out at Londrina State University, aiming at quantifying the oil and protein contents in two groups of soybean genotypes; estimating the phenotypic, genotypic and environmental correlations existent among oil, protein content and seed size, and identifying genotypes for direct human consumption with high protein content. The evaluated characters were Weight of a Hundred Seeds (WHS), expressed in grams/100 seeds, Oil Content (OC) and Protein Content (PC), expressed in %. In the experiment carried out in the field, OC ranged from 12 to 20.37 % and PC from 35.66 to 41.75% while in the experiment carried out in the greenhouse OC ranged from 12.26 to 21.79 % and PC from 32.95 to 41.56 % . The correlations... |

| In commercial corn production, small seed size is discarded from the seed lot and used as the animal feed, resulting in less profit to the seed industry. Therefore, the objective of this research was to increase seed size by seed pelleting methods. In this study, the types of filler pelleting materials and ratio of binder materials were investigated. The experiment was conducted at Seed Quality Test Laboratory of Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. Small seed size of hybrid corn that retained on grade 14/64” diameter sieve perforations were pelleted with seven different types and ratios of fillers (vermiculite, bentonite, pumice, calcium sulphate, calcium carbonate, charcoal and coconut) with four different types of binders... |
