Korelasi dan Analisis Lintas Karakter Agronomi Kedelai (Glycine max [L.] Merrill) Keturunan Persilangan Wilis X MLG 2521
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.
