Variabilitas genetik, heritabilitas dan kemajuan genetik beberapa karakter kuantitatif galur F3 kedelai hasil persilangan

Parameter genetik seperti keragaman genetik, heritabilitas dan kemajuan genetik diperlukan untuk merakit kultivar unggul. Untuk itu dialukan evaluasi keragaman genetik, heritabilitas dan kemajuan genetik populasi galur F3 kedelai dari 16 kombinasi persilangan dengan 6 tetua pada beberapa karakter kuantitatif diantaranya yaitu tinggi tanaman, jumlah cabang, jumlah polong isi, jumlah buku subur dan berat biji per tanaman. Penelitian untuk menyiapkan materi genetik dilakukan di Kebun Percobaan Fakultas Pertanian Universitas Brawijaya, Jatikerto, Malang pada tahun 2013-2016. Percobaan menggunakan Rancangan Acak Kelompk (RAK) dengan tiga ulangan. Populasi setiap galur F3 dan tetua pada setiap petak masing-masing 120 tanaman untuk setiap ulangan. Dari hasil keragaman genetik yang diamati, karakter tinggi tanaman, jumlah polong isi, jumlah buku subur dan berat biji per tanaman memiliki nilai keragaman genetik yang luas, sedangkan jumlah cabang memiliki keragaman genetik yang sempit. Nilai heritabilitas karakter pada kombinasi persilangan memiliki nilai sedang hingga tinggi yang berkisar antara 0,25-0,75. Pada karakter tinggi tanaman dari hasil persilangan galur (Anjasmoro x Tanggamus), (Anjasmoro x Grobogan), (Anjasmoro x UB2), (Argopuro x Grobogan), (Grobogan x Anjasmoro), (Grobogan x UB2), (UB2 x UB1), (UB1 x Argopuro) dan (UB1 x UB2) memiliki nilai heritabilitas sedang yaitu 0,46; 0,39; 0,37; 0,46; 0,46; 0,47; 0,46; 0,25; dan 0,47. Pada nilai kemajuan genetik dari 16 galur hasil persilangan, galur (UB2 x Tanggamus) memiliki nilai rata-rata kemajuan genetik paling tinggi yaitu 64,35%, sedangkan galur (UB1 x Argopuro) memiliki nilai rata-rata kemajuan genetik paling rendah yaitu 25,84%.ABSTRACT The F3 soybean progenies derived from 16 cross combinations with six parents were evaluated for their genetic variability, heritability and genetic advances of quantitative traits i.e. plant height, number of branches, number of pods, number of active nodes and seeds weight per plant.

The F2 progenies of crosses among three soybean varieties were evaluated with their parents at Ngale Experimental Farm, Ngawi, East Java during the dry season of 2011. The experi-ment was conducted in a randomized block design with three replications. The seeds of each F2 progenies and parents were planted in two rows of 4.5 m long. Plant spacing was 40 cm x 15 cm and each hill contained one plant. Among the characters studied, seed weight per plant, number of pods per plant and days to maturity had the highest coefficient of variability with the means of 52.6%, 48.2% and 41.9%, respectively. Whereas seed size, plant height and number of reproductive nodes had moderate values of 36.9%, 35.5% and 37.4%, respectively. Number of branches and days to flowering had the lowest variability of 11.7% and 15.3%, respectively. Number of pods per plant, days to maturity, plant height and seed size had high mean estimates of heritability coupled with high genetic advance. The genetic progress of these characters that would be obtained for one generation of selection was estimated 47.2%, 45.7%, 40.9% and 40.3%, respectively. Among the agronomic characters, plant height, number of pods per plant, seed size and days to maturity had the highest coefficient of variability associated with high heritability and genetic advance. Therefore, selection for high yielding with early maturity soybean genotypes based on plant height, number of pods per plant and seed size might be possible.

SUMMARYEighteen varieties of safflower were studied in a randomized block design with five replications. Data on fourteen quantitative characters were recorded. Appreciable variability was displayed by all characters, especially yield and number of heads/plant. The heritability estimates ranged between 65 and 98%.Seed (achene) yield gave a significant positive genotypic correlation with number of seeds/head, head width, bract width and oil content. The 100-seed weight was significantly negatively correlated with the number of seeds/head and plant height at maturity. The genotypic correlations between yield/plant and four other traits were partitioned into direct and indirect effects. The highest direct positive contribution to yield was given by plant height, which had also a positive indirect effect via number of heads. The direct effect of the number of heads/plant was negative and the indirect effect via head width was positive.

Management of purple blotch in garlic was carried out in 2005/06 and 2006/07 at horticultural farm of Regional Agricultural Research Station, Parwanipur in Complete Randomized Block Design with three replications. First year’s results indicated insignificant effect of fungicides on Percentage Disease Intensity (PDI) of purple blotch disease of garlic as number of sprays used seemed to be inadequate. Second year’s result revealed that two sprays of Bavistin @ 0.2% had lowest PDI value but at par to other different number of sprays of different fungicides except no spray of fungicide. Bulb yield was highest in two sprays of Dithane M-45 @ 0.3% followed by two sprays of Krinoxyl @ 0.15%, three sprays of Blitox-50 @ 0.3%. Plant height was insignificant and highest bulb weight was found with three sprays of Blitox-50 followed by two sprays of Bavistin. Two year’s combined results indicated that two sprays of Bavistin @ 0.2% had lowest PDI value and all others PDI values were at par except control. The highest bulb yield was given by two sprays of Dithane M-45 followed by three sprays of Bavistin. Plant height and bulb weight were insignificant. It can be recommended that purple blotch disease can be managed by spraying Bavistin @ 0.2% thrice at 15 days interval or any other tested fungicides to have less disease, higher bulb yield and more economic return.Nepal Agric.
