Abstract

Three yellow promising crosses (SC Sk126, SC Sk130 and SC Gz304) and two checks (SC162 and SC168) were evaluated in three trials, the first trial (B) for estimating grain yield at five research stations, the second trial (C) to estimate resistance to late wilt disease under artificial infestation at four research stations and the third trial (D) to estimate grain yield in farmers fields at eleven governorates during the period from 2018 to 2021. In that respect, the two promising hybrids (SC Sk126 and SC Sk130) were superior in both grain yield and stability as well as in resistance to late wilt disease. They also passed from distinction, uniformity and stability test (DUS). Consequently, the two hybrids have fulfilled all the Egyptian cross registration tests. Thus, they were registered as new commercial hybrids. The hybrid SC Sk126 was commercially named SC181 and the hybrid SC Sk130 was commercially named SC182.
