Enzymatic Markers

Isozymes of eight enzymatic systems were determined in 22 maize landraces from Latin America, 27 from Africa, and 1 composite, and were analyzed by multivariate analysis. Efficiency of hybridization in producing the composite was evaluated with enzymatic markers. The composite closely resembled the Mali ecotypes from which 60% of its genetic constitution was derived. Prediction of heterosis in yield as related to enzymatic differences in parents of a hybrid is discussed.Key words: Zea mays L., Latin America, enzyme variability, multivariate analysis, heterosis.

Maize Landraces

Any relative nutritional differences among the diverse maize (Zea mays L.) landraces traditionally maintained in the Greater Southwest are little understood. In this article, we investigate a range of nutritional traits of five indigenous maize landraces in the US Southwest based on different kernel endosperm types: pop, flour, flint, dent, and sweet. We present macronutrient and micronutrient values for accessions of each landrace grown in the same environmental grow-out experiment. Macronutrient values vary considerably across these endosperm accessions. Sweet and flour maize had higher values of fat and protein, whereas dent had the highest carbohydrate content. Sweet and flour maize were comparatively the best sources of micronutrients. Sweet maize yielded the highest values of potassium, thiamin, and magnesium, and flour kernels had the highest riboflavin and niacin content. These results indicate that the maintenance of diverse maize landraces had nutritional as well as ecological, symbolic, and culinary value in both the past and today. Compared to modern commercial maize standards, traditional southwestern maize landraces had a somewhat higher caloric value, many had higher vitamin and mineral content, and all accessions but dent displayed higher protein values. This suggests that southwestern maize-focused diets that included diverse landraces may have been more nutritious than previously understood.

The Mean

AbstractThe loss of agrobiodiversity is a topic of global impact. On a local scale, Lombardy, in the Alpine macro-Region, has lost more than 78% of its plant agrobiodiversity. Only four maize (Zea mays L. subsp. mays) landraces of Lombardy are registered in the European Register of Conservation Varieties. However, there are other maize landraces in Lombardy such as “Mais delle Fiorine”, which was characterized from an agronomic, morphometric, nutritional and genetic point of view in this research and then compared with the four other landraces already registered (“Spinato di Gandino”, “Rostrato Rosso di Rovetta”, “Scagliolo di Carenno” and “Nero Spinoso”). “Mais delle Fiorine” resulted richer in starch (81% ± 1.6) and zinc (35.8 ± 9.1 mg Kg−1) and lower in phosphorus (3256.7 ± 204.2 mg Kg−1). The kernels in the five landraces also differ in the mean shape that is obovate without beak. A genetic distinction between “Mais delle Fiorine” and the other varieties was observed, and in particular compared to “Nero Spinoso”, while “Scagliolo di Carenno” and “Rostrato Rosso di Rovetta” showed great similarities. As regards agronomical trials, “Mais delle Fiorine” can grow from the Po Valley (90 m a.s.l.) to the mountain environments of the Seriana Valley (also over 900 m a.s.l.) without significant differences in grain yield. In addition, this landrace would seem able to tolerate environments where there is a greater probability of water stress.

Penelitian tentang pengaruh pemberian produktivitas pupuk organik terhadap hasil Tanaman Jagung (Zea mays L) di tanah mineral penelitian ini di laksanakan pada bulan Februari sampai Mei, yang bertempat di Sungai Salak Kecsmstsn Tempuling Kabupaten Indragiri Hilir Provinsi Riau. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang disusun secara faktorial yang terdiri dari 2 faktor dan 3 ulangan. Faktor B adalah bokashi pupuk kandang yang terdiri dari 4 taraf yaitu B0 (tanpa pemberianpupuk kandang), B1 (5 ton/ha) dan B2 (10 tom/ ha), serta B3 (15 ton/ha) Parameter yang di amati adalah tinggi tanaman, panjang daun ke tujuh, berat brangkasan basah, berat berangkasan kering, berat tongkol pertanaman sampel, diameter tongkol , produksi per plot, dan berat 100 biji. Selanjutnya data yang di peroleh di olah secara statistik, apabila F hitung lebih besar dari F tabel di lanjutkan dengan uji lanjut Tukey HSD pada taraf 5%. Hasil penelitian menunjukan bahwa interaksi bokashi pupuk kandang dan varietas berpengaruh nyata terhadap berat tongkol dan produksi dan produksi per plot, akan tetapi tidak berpengaruh nyata terhadap tinggi tanaman, panjang daun ke tujuh, berat brangkasan basah, berat brangkasan kering , diameter tongkol dan berat 1000 biji. Untuk perlakuan bokashi pupuk kandang secara tunggal berpengaruh nyata terhadap terhadap diameter tongkol , akan tetapi tidak berpengaruh nyata terhadap tinggi tanaman, panjang daun ke tujuh, berat brangkasan basah, berat brangkasan kering, berat tongkol, produksi per plot, dan berat 1000 biji, perlakuan bokashi terbaik terdapat pada pemberian 15 ton/ha. Sedangkan perlakuan varietas secara tunggal berpengaruh nyata terhadap berat brangkasan basah, berat tongkol, dan produksi per plot seta berat 1000 biji, akan tetapi tidak berbeda nyata dengan tinggi tanaman, panjang daun ke tujuh, berat brangkasan kering, dan diameter tongkol. Varietass terbaik adalah NT 10
