Line R-4 segregated into half resistant (R) and half susceptible (S) plants
^aValues are mean of 10 plants, IT values in brackets denote rare scores on the same leaf
^bGeneral reactions were as follows: 0 to 0;: highly resistant (HR); 0;1 to 1: resistant (R); 1 to 2: moderately resistant (MR); 2 to 3−: moderately susceptible (MS); and 3− to 4: susceptible (S)
