Performance Of Bread Wheat (Triticum Aestivum L.) And Durum Wheat {Triticum Durum Desf.) Varieties Under Rainfed Condition At Gembu On Mambilla Plateau, Nigeria

📄 Project Abstract

Three field experiments were carried out during 1991, 1992 and 1993 rainy seasons at Gembu (6 degrees 55' N, 10 degrees 38' E and 1,500 m above sea level) on Mambilla Plateau, Nigeria to study the performance of bread wheat (Triticum aestivum L.) and durum wheat {Triticum durum Desf.) under rainfed conditions. The treatments consisted of 121 wheat lines/varieties (88 bread and 33 durum wheats) laid out in a 11 x 11 simple lattice design with two replications. Height in durum wheat ranged between 70.9 and 87.8 cm while in bread wheat, it was between 65.3 and 109.1 cm. Mean tiller number was 22 percent higher in bread wheat compared with durum wheat across the years. Within durum wheat total tillers ranged between 207 and 625 whereas among bread wheat, it was 251 and 751 across the years. Flowering was four days earlier in bread wheat than durum wheat when averaged over the three years. Among durum wheat flowering ranged between 57 and 99 days, while in bread wheat, it was 56 and 84 da...
