Determining the best ratio of maternal (B73) to paternal (MO17) inbred lines to produce seed corn hybrid of S.C704
Journal Title: International Journal of Farming and Allied Sciences - Year 2012, Vol 1, Issue 2
Abstract
In order to determine the best ratio of maternal and paternal inbred lines and study the effect of planting various ratios of grain corn maternal to paternal inbred lines on grain yield and yield components of 704 grain corn single cross, an experiment was conducted in Bardsir-Kerman, in 1388 (2009). A randomized complete block design (RCBD) with 3 replications was used to compare 4 various ratios of maternal to paternal inbred lines (conventional 2:4 (A); dense 2:4 (B); dense 1:4 (C); conventional 1:4 (D)). Ear length, ear diameter, number of kernels per row, number of rows per ear, cob percent, cob weight, Thousand kernels weight (TKW), fertilization percent, total kernels per ears and seed yield were measured. Results showed that most measured traits, specially the yield components, were affected by the ratios. Mean comparison shows no statistical significant difference among B, D with A. Therefore, due to better efficiency, the conventional 1:4 ratio with yield of 2.8 t/ha is recommended.
