Correlation and Peat Analysis of Leaf Characters and Physiology to yield to Four Environments of Organic Swallow Guano FertilizerABSTRACT. An experiment to estimate correlation and path analysis of leaf characters to yield of four micro environments (without organic fertilizer and three rate of organic fertilizer) was conducted at Arjasari Experiment Station, Agriculture Faculty, Padjajaran University from January 2003 to August 2003, in 26 soybean genotypes and Wilis at four levels of organic swallow guano fertilizer. The level of organic fertilizer were: without swallow guano, 225, 450, and 675 kg ha-1 swallow guano. Each environment was arranged in completely randomized block design, replicated two times, check genotype (wilis) was planted between six genotypes for each replication. Result of this experiment showed that: leaf number did not have any correlation wit net assimilation rate (NAR). Leaf angle (LA), stomatal length (SL) and stomata frequency (SF) had a negatively correlation with NAR, whereas DTDW and chlorophyll (Chl) were positively correlated to NAR: NAR, seed fiiling period (SFP) and dry matter accumulation rate (DMAR) were positively correlated to yield, and high path coefficient was found either between DTDW and NAR, or between SFP and yield.

Abstract

Soybean is one of the crops that produce seeds with high protein content, as well as used by the inhabitants of Indonesia. Domestic soybean production can not meet the needs of the national soybean thus needs to be improved, one through breeding varieties with superior. One important step in plant breeding is the selection. To save time and costs of selection, it is necessary to determine the estimated correlation between characters  and to determine the causal relationship between characters used path analysis. Through path analysis can be seen directly and indirectly influence between variables forecaster with the response variable. The purpose of this study to obtain information (1) correlation between characters agronomic towards production. (2) direct and indirect effects of agronomic between characters towards production. The research was conducted from October 2013 until January 2014 in the integrated field laboratory of the Faculty of Agriculture, University of Lampung and observations made in Laboratory of Seed and Plant Breeding, University of Lampung. Soybean seeds used were  F5 generation zuriat from Wilis x Mlg 2521,  Willis and Mlg 2521. The treatment laid out in a randomized block design,  2 replications. The results showed that  there was a positive phenotype correlation between character of days to flowering, plant height, number of branches, number of pods, weight of 100 grains with grain weight per plant and there was no correlation between day to harvesting with the seed weight per plant. Direct selection of the most effective  was through the number of pods because number of  pods have a direct effect almost equivalent to the correlation. The relationship between the number of pods  and weight of seeds per plant explained a real relationship. Keywords: correlation, path analysis, selection, soybean

Abstract

Heritability, potential ratio, and heterosis of soybean (Glycine max [L.] Merrill) resistance to soybean mosaic virus. The use of soybean cultivars with resistance to SMV is a way for controlling soybean mosaic disease. The objective of this research was to estimate the disease severity, the narrow sense heritability, potential ratio and heterosis of resistance character and number of pithy pods, number of healthy seeds, and healthy seeds weight per plant of ten F1 populations of soybean crossing result to SMV infection. The experiment was arranged in a randomized complete block design in two replications. Observed characters were disease severity, number of pithy pods, number of healthy seeds, and healthy seeds weight per plant. The result of this research showed that 1) the crossing combinations those which were resistant to SMV (lower disease severity) were Yellow Bean x Tanggamus, Tanggamus x Orba, and Tanggamus x Taichung, 2) the narrow sense heritability of disease severity was included in medium criteria, 3) number of pithy pods belonged to high criteria, and 4) number of healthy seeds and healthy seeds weight per plant were included in low criteria. The crossing combinations that had low estimation value of heterosis and heterobeltiosis of resistance to SMV infection were Yellow Bean x Taichung, Bean x Tanggamus and Tanggamus x B3570. Disease severity or resistance to SMV is influenced by genetic and environmental factors.
