| Abstract |
Effect of reciprocal cross is salient information for hybrid testing. Therefore, this
study aimed to assess the importance of reciprocal effects, attainable heterosis,
and their relationship, emphasizing on agronomic traits, yields, and yield
components of sweet-waxy corn F1 hybrids. 11 parental lines were used comprised of
3 super sweet and 8 waxy corns to generate 48 F1 progenies using North Carolina II
mating scheme. Parental lines, hybrids, and 3 check hybrid varieties were evaluated
at the Vegetable Experimental Farm, Khon Kaen University, Thailand in the dry
season (2017/2018). Reciprocal cross effect was existed for days to silking, plant
height, husked ear length, unhusked yield, and husked yield. Almost all traits
exposed quite a small contribution of reciprocal cross advantage, out of which both
unhusked and husked yields possessed higher contribution (13.7% or 2.03 ton ha-1
and 11.8% or 1.25 ton ha-1
, respectively). Reciprocal cross effects significantly impact
heterosis (both mid-parent heterosis (MPH) and high-parent heterosis (HPH) for all
traits observed as positively strong linear correlation coefficient were revealed. This
investigation suggests corn breeders to include reciprocal crosses in their any
mating design since it is imperative for high-yielding oriented breeding. |
