Study on Correlation of Seed Germination Percent of Two Sweet Corn Hybrids with Field Emergence and Some Measured Traits related to yield

Sweet corn is one of the crops that its production is increasing thorough the world. There are a few research about effect of initial germination percent of sweet corn seeds on field performance, so in order to assess the correlation of seed germination and vigor of sweet corn with seedling field emergence and some other yield related traits, this study was conducted as factorial experiment based on randomized complete block design in 3 replications at laboratory and field of seed and plant certification and registration institute in 2 years. The factors were 2 cultivars (PA213 and KSC403) and 4 initial seed germination levels (75,80,85 and 90%) and evaluated traits were seedling dry weight, radicle emergence percent, seedling field emergence percent, seedling emergence rate, leaf area, plant height, ear length, ear diameter, rows number per ear, seed number per row and 1000-seeds weigh. The results of correlation analysis indicated that there was a high positive correlation between seed germination ability and vigor with seedling field emergence and most of the measured traits.
