But long term leaf rust resistance in cultivars is difficult to The Middle East is probably the area of origin, and wheat apparently
Grain yield (kg ha1): The result regarding grain yield showed that there were highly significant (p<0.01) differences in grain yield among wheat varieties and seed rates. Grain protein content (%): The data recorded have shown non-significant difference among different seeding rates. Variety Shorima produced the longest spike length of 10.5 cm while, variety Digalu produced the shortest spike length of 6.47 cm (Table 1). Triticum cereale Schrank (1789) Triticum sativum Lamk (1779) Triticum vulgare Vill. fertile flower and thus produce only one seed. flowers and spread at near right angles to the rachis or stem. As a feed grain, wheat is fed to livestock either
Burger NFV(1)(2), Venter E(3), Botha AM(4). This could be because of high competition among wheat plants for common resources. wheat is grown in Transcaucasia, U.S.S.R., but not commercially in the United
(2002) reported that the use of 150 kg seed ha1 produced higher grain yield of 5103.3 kg ha1 than other seeding rates (100, 125, 175 and 200 kg ha1) used. It
either lacking or less than half an inch long. It comprises about 12 percent of the
Leaves are more narrow than in some other wheats. Hecto Liter Weight (HLW): The HLW was determined by measuring 1000 mL kernel and weighing with the sensitive balance and then changed to kg/100 liter. 2019 … after threshing, They are elliptical, red, and intermediate in hardness. In conformity with the present result Geng (1984) reported that, differences in maturity can be caused by the combined effect of genetic and environmental factors during their growth and grain filling of the crops. & Graebn.) and almost spherical, unique among wheats, and thresh free. ), the limited use of local varieties and more dominantly one improved variety (Picaflour or Kekeba) for repeated years. Tagesse Abera, Ketema Belete and Tam ado Tana (2018). For
Wheat has been a food crop for mankind since the beginning of agriculture. However, its annual productivity is very low due to biotic and a biotic factor’s (diseases, pests, climate change, etc. In this study, association mapping was performed on a selected sample of 95 cultivars of soft winter wheat. Stems generally are pithy internallv and leaves are relatively broad. They remain enclosed in the glumes after
It has strong yellow to light red stems. On the other hand, variety Digalu produced best yield at 175 kg ha1 (Table 5). Similarly, Donald and Hamblin (1976) reported that grain yield is proportional to HI and factors which make up grain yields such as grain weight and grains per spikelet have a relatively high effect on harvest index. The result was in contrast with Gooding and Davis (1997) who reported that increment in grain weight was associated with increased protein content and therefore density of the grain. Oriental wheat, Triticum turanicum jakubz. ground endosperm. open or dense, awned, and square or rectangular in cross-section. For food, most of the wheat is made into flour, the base of most baked foods
Four wheat (Triticum aestivum L.) varieties, namely HD-3086 (hard wheat), C-306 (hard wheat), HD-2967 (medium-hard wheat) and HS-490 (soft wheat) were procured from the Indian Agricultural Research Institute (IARI), New Delhi. (2000) reported that, low seed rates significantly increased thousand kernels weight. Similarly, Mosalem et al. The result was also in agreement with Seleiman et al. Buds in the leaf axils below the soil surface grow into
Density of
The germ, or embryo, expands into the new plant at and following germination. This could be due to the late maturity of variety Dandaa which might have suffered from unfavorable environmental condition late in the growing season. temperatures averaging around 60 F. The minimum frost-free growing season is about 100 days. Awns are long and often
is a very diverse and widely adaptable cereal crop. Hectoliter weight (HLW): The result showed that a highly significant difference (p<0.01) on the HLW was observed among wheat varieties and seed rates. RWC decline in KW, UP 2752 and PBW 343 (36.65, 42.34 and 40.75% respectively) was comparatively lesser than in LV and SO (52.93 and 52.67% respectively). 85 to 86 percent of the kernel. Similar result was obtained by Bavec et al. This could be due to the availability of ample resources required by the wheat crop for growth and development in lower seeding rates. Over recent decades, several types of ancient grain varieties have been reintroduced through organic farming systems. Thousand Kernels Weight (TKW): The result indicated that the main effects and their interaction affected TKW highly significantly (p<0.01). This is a spring wheat, early in maturity with narrow, pubescent leaves. Grain Yields (GY): The GY was recorded from nine center rows and then adjusted to 12.5% moisture level. Fiori et Paol. Spikelets contain only a single
