graminis Pers.:Pers.) and common root rot [caused primarily by Bipolaris sorokiniana (Sacc. in Sorok.) Shoem.]. The germplasm line has grain yield, days to maturity, test weight, kernel weight, grain protein content, and gluten strength similar to Neepawa and the recurrent parent BW90. P8913-V2A5 is heterogeneous for leaf rust reaction (caused by P. recondita Roberge ex Desmaz.) and, at an average height of 104 cm, is 5 cm shorter than Neepawa. HY358 and HY320, the recurrent parents of P8917-B4D4 and P8921-Q4C5, are high-yielding wheat cultivars with medium protein content, gluten strength, and kernel hardness. P8917-B4D4 is a white-seeded and P8921-Q4C5 is a red-seeded germplasm line. P8917-B4D4 has a resistant reaction to loose smut, a moderately resistant reaction to stem rust and common root rot, and a moderately resistant to moderately susceptible reaction to leaf rust. Apart from test weight similar to Neepawa, P8917-B4D4 has higher grain yield and kernel weight, and requires about 4 d more to mature. Grain protein content is less, and height is 12 cm shorter than Neepawa. P8921-Q4C5 has a resistant reaction to loose smut and is moderately resistant to stem rust and common root rot. Compared with Neepawa, P8921-Q4C5 has similar test weight, greater grain yield, a heavier kernel weight, and more resistance to leaf rust (resistant to moderately resistant); it is about 3 d later to mature. Grain protein content is less and height is 13 cm shorter than Neepawa. Small amounts of seed, as well as more detailed information on the performance of the germplasm lines BW90, HY358, and HY424, are available from the corresponding author.
