Untuk meningkatkan produksi kacang panjang, perlu penggunaan varietas unggul.
Perakitan varietas unggul dapat diperoleh melalui persilangan dua tetua yang
memiliki perbedaan. Hasil persilangan antargenotipe kacang panjang dapat dilihat
melalui keragaan yang ditampilkan pada generasi keturunan (F1). Pada hasil
persilangan antartetua yang berbeda dapat diharapkan terdapat keragaman antara hasil
persilangan. Penelitian ini bertujuan untuk melihat keragaan karakter agronomi,
keragaman dan nilai duga heritabilitas arti luas kacang panjang generasi F1 hasil
persilangan tiga genotipe. Benih yang digunakan adalah benih F1 kacang panjang
yang merupakan hasil persilangan antara testa Merah Putih x Hitam (AxB), testa
Hitam x Merah Putih (BxA), testa Hitam x Coklat (BxC), testa Coklat x Merah Putih
(CxA), benih tetua testa Merah Putih, testa Hitam, testa Coklat. Penelitian ini
dilakukan dengan Rancangan Kelompok Teracak Sempurna (RKTS) dan data
dianalisis dengan menggunakan, analisis ragam,dan dilanjutkan uji LSI (Least

semua variabel. Untuk keragaman genotipe karakter agronomi kacang panjang hasil
persilangan tiga genotipe adalah luas untuk variabel umur berbunga, umur panen

Abstract

To increase the production of beans, it is necessary to use of superior varieties. The
assembly of superior verieties can be obtained by intersecting the two elders who
have differences. The result of intersecting between genotype beans can be seen
through the performances shown on next-generation (F1). On the results of a cross in
a different between elders can be expected there is diversity between the results of a
cross. This research proposed to look at the performance, variability and value guess
heritability agronomic broad sense character beans generation F1 crosses of the results
of the three genotypes. The seeds used are F1 seed beans which are the result of a
cross between a Red-White x Black seed coat (AxB), Black x Red-White seed coat
(BxA), Black x Brown seed coat (BxC), Chocolate x Red-White seed coat (CxA), the
seed elder Red-White seed coat, the seed elder Black seed coat, and the seed elder
Brown seed coat. This research was conducted with complete randomized design
(RKTS), analyzed by using a analyse of varian, and continued with LSI (Least

Significant Increase). The results showed that the phenotype diversity of agronomic
characters of long bean genotypes of three interchanges result is spacious for all
variables. For the diversity of agronomic characters of long bean genotypes yield
crosses three genotypes are spacious for the variable age of flowering, harvest dried
pods age, number of pods of the plant, average number of pods of the plant, average
length of locul (castor beans), the number of total seed, weight of seeds, but to the
variable age harvest fresh pods, the number of stalks of flowers, the average length of
the pods of the plant, average number of plant locul (castor beans) and weights 100
seeds is narrow. Broad sense heritability value magnitudes of characters of
Agronomy resulting F1 generation long bean crosses of the results of the three
genotypes for the variable age of flowering and the average length of lokul is high,
harvest dried pods age variable, the number of pods of the plant, average number of
pods of the plant, and the number of total seeds is medium, variable age pods fresh
harvest, the number of stalks of flowers, the average length of the pods of the plant,
average number of locul (castor bean) plants, seed plants, weights and weight of 100
seeds is low.
Key words: keragaan, diversity, heritability, long beans, the F1 generation.}
