The presented work is conducted at research farm for the vegetable plant, Department of Horticulture and Landscape Design, Agriculture and Forestry college, University. of Mosul, Throughout the autumn growing season 2018/2019, the major aim of this work is to determining the correlation as well as the path coefficient analysis in seven genotypes of garlic which were (Sinjari, Mankyshi, Iranian, Bakistani, lacal va., Kristal and Nader) collected from different origin and local market. The resulted indicated that the trait's mean squares have been highly considerable with regard to all traits indicating wide genetic variability between genotypes. The genotype local va. was best in leaf length, head diameter of height and head weight, also the number of leaves for each one of the plant while genotype Kristal gave a higher value in total yield ha-1 and biological yield. The result indicated significant and positive genotypic and phenotypic association between leaf length and the total yield, biological yield, T.S.S (Total soluble solid), weight, length and clove diameter showed negative correlation genotypic and phenotypic significantly with head length and number of cloves/head, while leaf's length through number of leaves plant-1, head diameter, clove's weight, and total yield showed maximum positive direct effects on total bulb yield. Clove diameter viz leaf length, biological yield, head weight, T.S.S, head diameter, number of cloves/head, clove weight, as well as clove length showed maximum indirect effect on the total yield per hectare.

“…The basic pre-requisite for variety improvement is the presence of genetic variability in genetic stocks. In Nepal, Introduction, clonal selection and heterosis breeding are practiced for improvement of vegetatively propagated crops (Joshi, 2017).Clonal selection is a major breeding method for garlic which showed high degree of variation in bulb size, color, growth habits, plant height, number and size of the cloves, days to harvesting, resistance to storage capacity, dormancy and adaptation to agro-climatic situations (Singh et al, 2012).Variability observed among different clones of garlic is due to mutation providing opportunities through natural and human selection for adaptation to various growing environments (Singh et al,2018).Evaluation and characterization of preserve traits among garlic landraces is fundamental for their efficient utilization in plant breeding schemes and effective conservation programs (Lampasona et al, 2003).Its evaluation will identify landraces that could be useful to obtain cultivars using clonal selection to be used in breeding programs (Kumar et al, 2015).Wider adoption of short duration and high yielding variety to different agro-ecological zones is necessary to accelerate the garlic production in the country (KC et al,2004).To increase the production of garlic crop, there is an urgent need to screen the landraces to get more divergent cultivars for qualitative and quantitative traits. This study was therefore conducted with the objective of phenotypic characterization and assessment of genetic diversity of local garlic landraces using morpho-agronomic characters among thirty-seven landraces collected from different parts of the country.…”

A research was carried out at the field of National Agriculture Genetic Resources Centre (NAGRC), Khumaltar, Lalitpur, Nepal in 2019 with the objective of phenotypic characterization and genetic diversity assessment of thirty-seven local garlic landraces. The phenotypic diversity was assessed based on fifteen qualitative and nine quantitative characters by sing non replicated rod row design following the descriptors developed by IPGRI, 2001. Descriptive statistics were calculated by using MS Excel 2016 and UPGMA clustering and PCA was done with MINITAB-17. The diversity index (H’) and coefficient of variation for different traits ranged from 0.54-0.96 and 16.89-87.85, respectively. Four clusters identified and CO 10307, CO 10482 and CO 10615 of fourth clusters were superior in terms of quantitative characters. Five principal components contributed95.2% of the cumulative variance. This result will be helpful for breeder and researchers to comprehensively understand the agro-morphological characters as well as diversity of the Nepalese garlic collection.

Bawang merah (Allium cepa L. var aggregatum) salah satu komoditas hortikultura banyak di konsumsi. Peningkatan permintaan dalam kuantitas dan kualitas untuk komoditas ini meningkatkan ketersediaan varietas unggul. Penelitian dilakukan untuk menduga keragaman genotipe dan fenotipe serta nilai heritabilitas karakter pertumbuhan, komponen hasil dan hasil bawang merah di tiga lokasi dataran tinggi (Lembang 1.250 m dpl, Kab. Bandung Barat; Pacet 971 m dpl, Kab. Bandung; dan Samarang, 970 m dpl, Kab. Garut). Penelitian dilaksanakan dari September sampai Nopember 2019. Materi genetik yaitu 12 genotipe bawang merah terdiri dari 7 klon: B1, B19, B63, B72, B77, B102, dan B222, serta 5 varietas: Trisula, Bali Karet, Maja Cipanas, Bima Brebes dan Sumenep. Rancangan percobaan menggunakan Rancangan Acak Kelompok (RAK) dengan 3 ulangan. Hasil analisis ragam menunjukan genotipe berpengaruh sangat nyata terhadap seluruh karakter pertumbuhan, komponen hasil, dan hasil. Nilai koefisisen keragaman genotipe dan fenotipe yang tinggi diperlihatkan oleh karakter persentase tanaman berbunga (48,10 % dan 49,01 %), berat basah per umbi (29,71 % dan 30,87 %), dan berat kering per umbi (33,17 % dan 34,29 %). Nilai duga heritabilitas arti luas (Hbs) karakter pada 12 genotipe bawang merah berkisar antara 45,08-96,30 %. Semua karakter yang diuji memiliki nilai heritabilitas tinggi kecuali untuk karakter jumlah daun per rumpun nilai heritabilitasnya sedang. Seleksi bawang merah di dataran tinggi dapat dilakukan pada generasi awal.AbstractShallots (Allium cepa L. var aggregatum) are one of the most widely consumed horticultural commodities in Indonesia. Increased demand in quantity and quality for this commodity improved availability varieties. A study was conducted to estimate variability of genotypes and phenotypes as well as the heritability value of growth characters, yield components, and yields of shallot at three highland locations (Lembang 1.250 m asl, West Bandung District; Pacet 971 m asl, Bandung District; and Samarang 970 m asl, Garut District). The research was conducted from September to November 2019. The genetic material studied was 12 genotypes of shallots consisting of 7 clones: B1, B19, B63, B72, B77, B102, and B222, and 5 varieties: Trisula, Bali Karet, Maja Cipanas, Bima Brebes, and Sumenep. Every experiments in all locations was arranged in Randomized Block Design (RBD) with 3 replications. The analysis of variance results showed that the genotype had a very significant effect on all growth characters, yield components, and yields. High variation coefficient values of genotype and phenotype was found in the character of percentage of flowering plants (48.10% and 49.01%), freshweight per bulb (29.71% and 30.87%), and dry weight per bulb (33.17% and 34.29%). All characters tested had a wide phenotific variability. The estimated value of heritability (broad meaning) of the characters in 12 shallot genotypes ranged from 45.08 to 96.30%. All characters tested has high heritability except for the number of leaves per clump the heritability was moderate. The study is the shallot selection in the highlands can be carried out in the early generations.
