Abstract
Breeding lines C29-A7 and PMR Honeydew, and Chilton were used as donor parents in crosses with Kalakesel and Greenqueen Hami-melons.
Breeding lines 6-13, 6-4 and 6-1 resulted from single backcrosses to their respective Hami-melon parent followed by selection during inbreeding for resistance to powdery mildew, downy mildew, gummy stem blight and a root rot of unknown origin.
Lines 6-13 and 6-4 have intermediate resistance to powdery mildew and downy mildew; line 6-1 has intermediate resistance to gummy stem blight.
Line 1-21, selected from the cross of line 6-4 x Blacksweet Hami-melon, is late maturing and is suited for open-field production; it is highly resistant to powdery mildew, has intermediate resistance to downy mildew, and is tolerant of the root rot.
Line 1-45, selected from a cross of line 6-13 x R. Hong-xincui Hami-melon, is for greenhouse production.
