Identification of sequence-characterized amplified regions (SCARs) markers linking resistance to powdery mildew in chilli pepper (Capsicum annuum L.)
Powdery mildew disease in chilli pepper caused by Leveillula taurica has been affecting chilli pepper grown in greenhouse and open fields. Inheritance of powdery mildew disease resistance is complex and least understood. In the present study, we identified SCAR markers using F2 mapping populations developed from a cross between a resistant parental line ‘Odisha Local' and a parental line susceptible to powdery...

Genetic variability in agronomic traits and associations in sorghum [(Sorghum bicolor (L.) Moench)] genotypes at intermediate agro-ecology sorghum growing areas of Ethiopia
The present study consists of 14 sorghum genotypes evaluated at Bako, Jimma and Mechara research centers to study genetic variability and interrelationships of traits with grain yield. The experiment was conducted by using randomized complete block design (RCBD) with three replications during 2014 and 2015 main rainy season. Data on important agronomic traits were collected. The combined analysis of variance (ANOVA)...

Genetic variability of some yield and yield related traits in recombinant inbred lines of tef [Eragrostis tef (Zucc.) Trotter] at Laelay Maichew District, Northern Ethiopia
Tef [Eragrostis tef (Zucc.) Trotter] is a tetraploid almanac plant which belongs to the grass family, Poaceae and plays a vital role in the Ethiopian national food. In this study, thirty-four F2 derived F7 recombinant tef inbred lines, two standard (Kora and Quncho) and one local checks were field evaluated for genetic variability in grain yield and yield related characters at Axum Agricultural Research Center in 2014...

Economic and operational analysis of tomato mechanized harvesting systems for industrial processing
The determination of the cost of agricultural production is an important tool for controlling and managing productive activities and generating information to support decision-making. The objective of this work was to make technical and economic evaluations of three mechanized tomato harvesting systems for industrial processing through the study of times, movements and the determination of operational costs. The...

Priming of Urochloa brizantha cv. Xaraés seeds
Priming is one of the several physiological methods used to increase the performance of seeds. To evaluate the effects of priming, seeds of Urochloa brizantha cv. Xaraés were primed under different osmotic potentials (ys = 0.0; -0.5; -1.0 and -1.5 MPa) and temperatures (15 and 25°C) for 24, 48, 96 and 144 h. The germination percentage and germination speed index were evaluated, in a completely randomized...
