Evaluation on Agronomical Characters and Combining Ability on Yield Characters of Some Sweet Corn Inbred Lines Using Topcross Method

  • Nguyễn Thế Hùng

Abstract

A total of eight sweet corn inbred lines was evaluated for their combining ability using topcross method in a lines x tester scheme. Twelve topcross hybrids produced by crossing 6 outstanding sweet inbred lines with 2 testers were evaluated in Autumn - Winter season 2008 and Spring season 2009 at Hanoi Agricultural University. The lines Đ3 and Đ27 exhibit good general combining ability. Two hybrids were identified slightly higher than the check cultivar, Sugar 75, in terms of fresh corn yield, i.e. Đ5 x Đ3 (15.24 tons/ha) and Đ8 x Đ27 (15.04 tons/ha). The percentage of Brix of these hybrids is similar to the check
