1. Resistance to Striga hermonthica in a maize inbred line derived from Zea diploperennis. 2. Other, more closely inbred lines , produce short-lived, unhealthy dogs. 3. This is especially true between inbred lines . 4. Commonly used populations are recombinant inbred lines ( RILs ), linkage mapping " . A 5. Quality analysis ( QC analysis ) is used to maintain the purity of inbred line . 6. F1 crosses in animals can be between two inbred lines or between two closely related species or subspecies. 7. This new cross descended from four distinct inbred lines , and was even more vigorous than either of its parents. 8. The solution for this problem would be production of recombinant chromosome substitution line, or stepped aligned recombinant inbred lines . 9. Jones'method produced a double-cross hybrid, which requires two crossing steps working from four distinct original inbred lines . 10. However, the modern hybridization process, where one inbred line of corn is crossed with another, developed from this early work in cross breeding.
