“…The present results are also in agreement with Ali and Khan (1998) and Hamada et al (2002) for this trait. However results of this study differ with Kumar et al (2003), Dhayal and Sastry (2003) and Chowdhry et al (1999) who reported non-additive genetic effects for this trait. This may be due to differences in the genetic material used and environmental conditions under which the was the best combiner with maximum GCA effects (1.90) whereas Aas-11 (-1.78) was the poorest general combiner ( Table 5).…”

The economic value of wheat grain is determined by morphology, texture and size of grain. Very little knowledge is available about the genetic inheritance pattern of the physical characteristics of wheat grain. The mechanical properties of wheat kernel have direct or indirect link on the milling and baking quality of wheat. Six bread wheat genotypes/lines were crossed in all possible combinations in order to assess the physical properties. Additive type of gene action was involved in number of spikelets per spike, spike length, number of grains per spike, grain weight and grain area. Therefore, selection of superior plants can be done in early generations for development of better wheat genotypes. Grain yield per spike, grain width, grain length, grain height and grain sphericity having nonadditive type of gene actions clearly indicated that selection of superior plants should be postponed to later generations. The genotype 9481 was the best general combiner, while among the combining ability in most of the prominent traits. This study will be useful for wheat breeders to develop high yielding genotypes with better grain architecture to improve the milling and baking quality of bread wheat.

to investigate the effect of seed rate and Variety of wheat (Triticum aestivum L.) on grain productivity under New Halfa environment. The treatments consisted of three seed rates (119kg/ ha, 143kg/ ha and 167kg/ ha) and two cultivars (Condor (early mature) and Bohin (medium mature). A complete randomized block design (CRBD) with four replications was used. The results revealed that the lesser seed rate (119 kg/ ha) had a lower grain yield compared with the mid seed rates (143kg ha-1) or highest seed rate (167kgha-1). Cultivars had significant differences in the total seed yield. Condor gave the highest seed yield. It could be concluded that the seed rate of 143 kg or 167 kg/ha recommended to improved seed yield in New Halfa area of Sudan. Contribution/Originality:This study is one of the very few studies which have investigated the effect of seed rate and Variety of wheat (Triticum aestivum L.) on seed yield under New Halfa environment, Sudan.

Optimum seeding rate and row spacing are important for uniform crop establishment and harvest of quality seed. Field experiment was conducted at three locations in 2014 and 2015 to study the influence of seed rate and row spacing on seed multiplication factor and yield of durum wheat. Triplicate split plot design was used. The highest seed yield was found at a seed rate of 125 kg ha−1 with a row spacing of 10 cm in 2014 but not significant with the seed rates of 100 kg ha−1 at 10 cm spacing, 75 kg ha−1 at 20 cm row spacing in 2014, and 150 kg ha−1 at 10 cm row spacing in 2015 at Debre Zeit. At Chefe Donsa, the highest seed yield (4.75 ton) was harvested at a seed rate of 100 kg ha−1. At Minjar, seed yield was not affected by seeding rate. Seed multiplication factor was higher at a seed rate of 50 kg ha−1 and spacing of 20 cm at Debre Zeit. At Chefe Donsa, the highest seed multiplication ratio (97.3) was observed in 2015 at a seed rate of 50 kg ha−1 with row spacing of 30 cm. Seed multiplication factor decreased with increasing seed rate at all testing locations. Sowing of 100 kg seeds per hectare with 20 cm spacing gave optimum seed yield over the testing locations. With limited seed availability of nucleus seed, 50 and 75 kg ha−1 with a spacing of 20 cm is appropriate to upsurge seed multiplication ratio.
