“…It is likely that the ‘Kitami-94’ line will be useful for basic research to elucidate the mechanisms of PPO activity and resistance to WYMV. Kobayashi et al (2020) produced lines with broken linkage between Ppo-D1b and WYMV resistance, using 960 plants from recurrent back cross progenies. With the help of this report we have begun to break the linkage of undesirable traits with Qym1 on 2DL in ‘Kitami-94’.…”

Kitahonami' is a soft red winter wheat (Triticum aestivum L.) cultivar that has high yield, good agronomic performance and good quality characteristics. It currently accounts for 73% of the wheat cultivation area of Hokkaido the northern island in Japan and 42% of Japan's overall wheat cultivation. However, this cultivar is susceptible to Wheat yellow mosaic virus (WYMV). WYMV has become widespread recently, with serious virus damage reported in Tokachi and Ohotsuku districts, which are the main wheat production areas in Hokkaido. Here, we report a new wheat breeding line 'Kitami-94', which was developed over four years by repeated backcrossing with 'Kitahonami' using DNA markers for WYMV resistance linked to the Qym1 and Qym2 from 'Madsen'. Basic maps of Qym1 and Qym2 were created and used to confirm that 'Kitami-94' reliably carried the two resistance genes. 'Kitami-94' demonstrated WYMV resistance, and had agronomic traits and quality equivalent to 'Kitahonami' except for higher polyphenol oxidase activity and lower thousand grain weight. 'Kitami-94' may be useful for elucidating the mechanism of WYMV resistance in the background of 'Kitahonami', and for developing new cultivars.
