对陕西省玉米黄改系主要农艺性状的配合力分析结果表明 :5个黄改系 1 0个性状的配合力各有所长 ,但单株产量和出籽率均不及原先的黄早四。通过对 5个黄改系可利用的性状的综合评价 ,提出要加强“自育黄改系× 478及其改良系”这一杂交模式在陕西及华北夏玉米区的进一步研究和利用。
The analysis of the combining ability of main agronomic traits of maize transformation system in Shaanxi Province showed that the combining ability of 10 traits in 5 yellow lines had its own advantages, but the yield per plant and the seed yield were lower than those of the original Huangzao 4. Based on the comprehensive evaluation of available traits of five yellow lines, the further research and utilization of the hybrid pattern of “self-rearing yellow lines × 478 and its improved lines” was proposed in summer maize area of Shaanxi and North China.
