KOMPONEN KERAGAMAN SIFAT-SIFAT YANG BERHUBUNGAN DENGAN KETAHANAN TERHADAP PENGGEREK POLONG (Etiella inckenella Treitschke) PADA TANAMAN KEDELAI (Glycine max L. Merril)
Abstract: One of main problems
in increasing soybean production is the attack of pests such as soybean pod borer
(Etiella zinckenella Treitschke). The objectives of this research was to
determine the variance components and heritability of various characters associated
with resistance to soybean pod borer. A
field experiment was established by randomized complete block design where six
cultivars of soybean including Gema, Grobogan, Kaba, Willis, lines KM 19 and KM
25 are planted in plots of 2.5 m in
length and 2 m in wide. The experiment
was conducted at the Center for Integrated Seed production at Pasir
Pengaraian, Riau Province. The
parameters observed were number of larva per plant, percentage of damage pods
per plant, percentage of damage seeds per plant, number of pods per plant,
number of seeds per plant, yield per m2, weight of 100 seeds dry and additional
observations. The data were analyzed by using analysis of variance and then the
components of genetic and phenotypic variance and heritability were calculated.
The results showed that all parameters were relatively narrow genetic
variation. Phenotypic variation was narrow for number of larva per plant,
percentage of attacked pods and weight
of 100 seed dry, and considered wide for the percentage of seeds damage, number
of filled pods, number of seeds per plant, and yield per m2. Broad sense heritability values were high for
percentage of attacked pods, the percentage of seeds damage, number of filled
pods, number of seeds per plant, weight of 100 seed, and very low for number of larvae per plant and
yield per m2. Genotype Willis and KM 19 are two potential cultivars to be
chosen as a parent to develop resistant cultivars to soybean pod borer.
