Is Every Toric Variety an M-variety? [PDF]

manuscripta mathematica, 2006
A complex algebraic variety X defined over the real numbers is called an M-variety if the sum of its Betti numbers (for homology with closed supports and coefficients in Z/2) coincides with the corresponding sum for the real part of X. It has been known for a long time that any nonsingular complete toric variety is an M-variety.

Diversity between and within farmers’ varieties of tomato from Eritrea [PDF]

, 2011
Tomato yields in Eritrea are low (15 Mg/ha) compared with 19 Mg/ha in Africa and 27 Mg/ha worldwide. This is partly caused by poor quality of varieties used.
