check row
1.Analysis was conducted on the yield and ear kernel structure characteristics of 33 Yugoslavia hybrids and trait comparison was carried out with the domestic control check hybrid. The results were as fellows: the kernels per row and the 1000 kernel weight were the direct factors to determine the yield of the Yugoslavia hybrids, the ear length and the rate of grain yield indirectly affected the hybrid yield through the kernels per row, row numbers per ear had little effect.
