Autor: Zewdie Bishaw, Paul C. Struik, A. J. G. van Gastel

Publikováno v: African Journal of Agricultural Research, 9(39), 2948-2963
African Journal of Agricultural Research 9 (2014) 39

Analysis of spatial diversity, temporal diversity and coefficient of parentage (COP) were carried out along with measurements of agronomic and morphological traits to explain on-farm diversity of modern varieties or landraces of wheat (Triticum aesti

Correlation and Path Coefficient Analyses of Laboratory Tests as Predictors of Field Emergence in Lentil (Lens culinarisMedikus)

Autor: M. El Balla, M. Makkawi, A. J. G. van Gastel, Zewdie Bishaw

Publikováno v: Journal of New Seeds. 9:284-302

Field establishment in Lentil is a key determinant in its production. To investigate the prediction of field emergence through various laboratory parameters, correlation studies between seed vigor tests and field emergence were carried out across two

Seed Quality Control in Developing Countries

Autor: Tony J. G. van Gastel, Bill R. Gregg, E. A. Asiedu

Publikováno v: Journal of New Seeds. 4:117-130

Quality, in terms of purity and ability to establish a field stand of the desired plants, is the primary value factor of seed and a concern for every seed supplier. Thus, a primary task of the seed industry is achieving quality in production, maintai
