The expression of leaf rust resistance in wheat lines containing Lr12 and Lr13
(University of the Free State, 1995-11-30)
Monogenic resistance in wheat (Triticum aestivum L.) to leaf rust, caused by Puccinia
recondita Rob. ex. Desm. f. sp. tritici, has generally not been durable. One strategy of
attaining durable resistance to rust diseases ...

Identification of genetic distances and heterotic groups of inbred maize (Zea mays) lines using DNA fingerprinting
(University of the Free State, 1999-12)
English: AFLP (Amplified Fragment Length Polymorphism) analysis has found widespread
use in DNA fingerprinting because of its relative simplicity, low cost and high
marker output. AFLP analysis also does not have the ...
