“…Previous studies have illustrated that all seven Ns chromosomes from P. huashanica that have been introduced into common wheat exhibit excellent characteristics with regard to disease resistance and agronomic traits. Examples include 2Ns, 3Ns, 4Ns, and 5Ns disomic addition lines and a 1Ns (1D) disomic substitution line with resistance to stripe rust [ 35 , 36 , 37 , 38 ], 1Ns and 7Ns disomic addition lines with resistance to leaf rust [ 24 , 39 ], 6Ns and 7Ns addition lines maturing earlier than their wheat parents [ 25 , 40 ], and a 2Ns (2D) disomic substitution line with a high level of resistance to wheat take-all [ 41 ]. In addition, a 4Ns disomic addition line has been found to have enhanced tiller numbers [ 38 ], and a 1Ns disomic addition line was reported to exhibit increased storage of microelements in seeds [ 42 ].…”
