Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Leaf-rust highly resistant introgressive wheat lines have been studied genetically using effective Lr genes from Thatcher’s isogenic lines and “Kazakhstanskaya 126” monosomic lines. Resistance genes Lr9, Lr19, Lr9, Lr24 and Lr26 in line L-344 were shown not to be allelic. Lr9 and Lr26, allelic genes conferring resistance to leaf rust have been identified in line L-345. The “leaf rust” resistance gene in the L-344 line is localized on a morphologically marked 5A chromosome, while the same gene in the L-345 line is located on 2B and 4B chromosomes.
