In 2003, 86 S4-lines were crossed, as females, to line SK-5054 as a male tester to produce 86 top crosses. These testcrosses along with the check hybrid SC-10 were evaluated in 2004 for grain yield, number of days to mid – silking and plant and ear heights at three different locations UR - http://nile.enal.sci.eg/EALE/2007/JARKU/3307/3/586.pdf ER -
