Abstract

ABSTRACTSeed size characters measure represent an important factor of production and determinant in physical indicator to determine consumer fascination as completely seed. Genetic Variability represent the breeder seeds basis to find a new variety that genetically having high yield. This research aim to to know seed size measure character genetic variability from F2 soybean, crossing between big seed size measure parental with small seed size measure parental. Result of the research showed that there are wide of genetic variability. Genetic variability of vascular bundle system is an important new varieties parameter in recombining genetically high yield. A hundred seed weight, seed length, seed thickness and seed width had wide genetic and phenotypic variabilityKey words: genetic variability, seed size, F2, soybean

Abstract

This study was conducted to determine the pattern characteristics of legumes in the vegetative phase by using the Relative Growth Rate, Net Assimilation Rate (LAB), and Leaf Area Ratio (LTR). Where the LTR is dry matter production efficiency index, is a measure of the efficiency of clean LAB leaf area and the NLD is the quotient of leaf area to total plant dry weight. The experiment was conducted in field trails and laboratory PandeglangSMKN 2 Faculty of Agriculture, University of Sultan AgengTirtayasa. Starting in September to December 2012. Trial ordered by a single factor randomized complete block design (legume crops). Type of legume crops are planted consist of the three types, namely : soy beans, green beans, and peanuts. For purposes of analysis vegetative growth phase was observed (destructive) six times. The result showed that the characteristics of three types of legume crops : soy beans, peanuts, green  beans, and each has different characteristics. Where the LTR and LAB in legumes has decreased, and the soy bean crop legumes NLD slightly increased, while the peanuts and green beans decreased with increasing age of the plant.
