Korelasi Dan Analisis Lintas Komponen Komponen Hasil Kedelai Famili F6 Hasil Persilangan Wilis X B3570
Abstract: Soybean is an
alternative stapple food which use by all people in Indonesia. However,
domestic soybean production does not meet the needs of the national soybean. To
meet the needs done, it important to assemble the soybean breeding to improved
the noble varieties. Plant breeding is largely determined by the ability of
breeders to select. Selection can be done by estimating the correlation
coefficient between the components of the results and outcomes. To determine
the causal relationship between yield and yield components used path analysis.
Path analysis of correlation coefficient will break into the direct and
indirect influence. The purpose of this study are to determine (1) the
correlation between the components of the results and outcomes; (2) direct and
indirect influence between the components of the results and outcomes. The
experiment was conducted from March to July 2014 in field trials of POLINELA
(Lampung State Polytechnic) and in Seed Laboratory of University of Lampung.
Soybean seed used is the result of crossing Wilis F6 generation x B3570. Treatment
arranged in a perfect randomized group design with two replications. The
results of correlation analysis showed correlation great and positive value
indicated by the component total number of pods per plant and grain weight per
plant (0.80 *), hundred grain weight and grain weight per plant (0.72 *), and
the number of productive branches and grain weight per plant (0.57 *). Results
of the analysis showed cross large direct effect on the character of the total
number of pods per plant to grain weight per plant (0.89), which is almost as
large as the correlation (0.80 *). Then the correlation coefficient was
actually measure the degree of closeness of their relationship. Therefore, the
selection is based on the total number of pods will be very effective to get
genotype expectations that have high yields.
