Recombinant inbred (RI) lines offer several advantages for detecting quantitative trait loci (QTLs), including increased precision of trait measurements, power for detection of additive effects, and resolution of linked QTLs. This study was conducted to detect and characterize QTLs in maize for flowering and plant height and to compare QTL detection in an early (F2:3) generation of the same population. One hundred and eighty-six RIs from a cross between inbred lines Mo17 and H99 were evaluated in a replicated field experiment and analyzed at 101 loci detected by restriction fragment length polymorphisms. QTLs were identified by single-factor analysis of variance. A total of 59 QTLs were detected for plant height, ear height, top height, anthesis, silk emergence, and anthesis to silk interval. Individual QTLs explained 2.2–15.4% of trait variation, and multiple models including all QTLs detected for a trait explained up to 52.5% of the phenotypic variation. Comparison of QTLs detected with 150 F2:3 lines from the same population indicated that 16 (70%) of the 23 F2:3 QTLs were also observed in the F6:7 generation. Parental effects were consistent across generations. At 14 of the 16 QTLs detected in both generations, genetic effects were smaller in the F6:7. Also, some QTLs detected in the F2:3 were resolved into multiple linked QTLs in the F6:7, indicating the additional power of RI populations for mapping, with important implications for marker-assisted selection as well as map-based cloning of QTLs. Key words : Zea mays, RFLP, plant breeding, genetics, recombination.

ABSTRACT The purpose of this study is to determine the effect of interaction and the main influence of vermicompost and NPK Pearl 16:16:16 on the growth and yield of celery plants. This research was carried out for four months, from August to November 2018. This research used a factorial completely randomized design (RAL) consisting of two factors, where the first factor was vermicompost fertilizer (K) consisting of 4 levels, namely 0, 60, 80, 100 g / polybag and the second factor is NPK Pearl 16:16:16 (N) fertilizer consisting of 4 levels, 0, 0.8, 1.6, 2.4 g/polybag. The observation parameters in this study were plant height (cm), relative growth rate (g), root volume (cm3), number of tillers, number of midribs, wet weight of crop (g), and age of harvest (days). The last observation data were statistically analyzed and continued with a BNJ follow-up test at the 5% level. The results showed that the interaction between vermicompost and NPK Pearl 16:16:16 fertilizer significantly affected plant height from week two to week seven, the relative growth rate in the first week, root volume, number of tillers, number of fronds and wet weight per plant. The best treatment is K3N3 (K3 vermicompost fertilizer = 100 g /polybag and NPK Pearl 16:16:16 N3 = 2,4 g/polybag), but it has no significant effect on the age of harvest and the main effect of vermicompost and NPK Pearl 16:16: 16 significantly affected plant height, relative growth rate, root volume, number of tillers, number of midribs and wet weight of the crop, with the best treatment being K3 (vermicompost fertilizer 100 g/polybag) and N3 (NPK Pearl 16:16:16 2,4 g/polybag). Keywords: Celery, Vermicompost, NPK pearl 16:16:16

This study aims at determing the response of growth and production of peleng vegetables to the application of liquid organic fertilizer in various mulch. The study was conducted on land located in Simalingkar A Medan with a height of ± 32 m above sea level, began from May to August 2017. The research method used a factorial randomized block design with 2 factors. The first factor is the dose of NASA liquid organic fertilizer (P) which consists of 3 levels of treatment, namely: P0 = control, P1 = 3 ml / l water and P2 = 6 ml / l water. The second factor is the provision of mulch (M) which consists of three types, namely: M0: without mulching, M1: rice straw mulch and M2: black silver plastic mulch (MPHP). The results showed that the treatment of NASA liquid organic fertilizer up to 6 ml / l water significantly increased plant height, number of leaves, fresh weight of plants per sample, fresh weight of plants per plot, dry weight of plants per sample and dry weight of plants per plot, but differed not markedly on the relative growth rate of plants. The treatment of organic mulch and black silver mulch significantly increased plant height, number of leaves, fresh weight of plants per sample, fresh weight of plants per plot, dry weight of plants per sample and dry weight of plants per plot, but not significantly different to the relative growth rate of plants. The interaction between NASA's liquid organic fertilizer treatment and mulch administration had no significant effect on plant height, number of leaves, plant fresh weight per sample, plant fresh weight per plot, plant dry weight per sample, plant dry weight per plot and relative plant growth rate

AbstrakPenyemaian laban dengan menggunakan metode ekstraksi biji belum banyak dilakukan dan perlu penambahan bahan pembenah tanah untuk meningkatkan pertumbuhan semai. Penelitian ini bertujuan untuk mengetahui pengaruh ekstraksi biji dan kombinasi media tanam terhadap penyemaian laban (Vitex pinnata L. Kuntze). Penelitian ini menggunakan rancangan acak lengkap dengan 2 faktor perlakuan yaitu ekstraksi biji (A0= ekstraksi basah dan A1= ekstraksi kering) dan kombinasi media tanam (M0= Tanah, M1= tanah + pasir, M2= tanah + kompos, M3= tanah + cocopeat), masing-masing diulang sebanyak 3 kali. Data yang diperoleh dianalisis dengan menggunakan uji varian (ANOVA) dengan taraf kepercayaan 95%, uji lanjut menggunakan uji Duncan pada taraf kepercayaan 95%. Hasil penelitian menunjukkan pada perlakuan ekstraksi biji kering dapat meningkatkan rata-rata persentase berkecambah sebesar 65,83% dan kecepatan tumbuh biji sebesar 3,25%, namun belum dapat meningkatkan pertambahan tinggi tanaman, jumlah daun, berat basah akhir, berat kering akhir dan laju pertumbuhan relatif. Kombinasi jenis media tanam tanah + kompos dapat meningkatkan persentase berkecambah sebesar 73,33% dan kecepatan tumbuh benih sebesar 3,40%. Penelitian ini sangat penting dalam penyiapan bibit siap tanam dalam budi daya V. pinnata.Abstract Seedling using seed extraction method has not been explored much and it needs to add soil enhancers to increase seedling growth. This research aims to determine the effect of seed extraction and combinations of planting media to seeding Laban (Vitex pinnata L. Kuntze). This research used a complete randomized design with two treatment factors namely seed extraction (A0= wet extraction, A1= dry extraction) and combinations of plant medium (M0= soil, M1= soil + sand, M2= soil + compost, M3= soil + cocopeat) were repeated three times each. The data were analyzed by using variance test (ANOVA) at 95% level of confidence and continued using Duncan test at 95% level of confidence. The result showed that the dry seed extract treatment increased the average of germination percentage by 65.83% and seed growth rate about 3.295% but could not increase plant height, leaf number, final wet weight, final dry weight dan relative growth rate. The combination of planting media  + compost increased the germination percentage by 73.33% and the seed growth about 3.40%, but not yet able to increase plant height, leaf number, final wet weight, final dry weight and relative growth rate of laban plant. This research is very important in preparing ready-to-plant seedlings in V. pinnata cultivation.
