通过对甘肃省推广面积在10万亩以上的15个高产优良春小麦品种(系)的对比种植,分析了品种的抗条锈性,对12个品种(系)与产量有关的11个数量性状进行了相关、通径分析。结果表明,穗长、穗粒重、单株粒重、穗粒数及千粒重是构成产量的主要因素;穗长与每穗有效小穗数应是田间选择的主选性状。文中还对抗条锈病的育种途径进行了探讨。
The stripe rust resistance of 15 high yielding elite spring wheat cultivars (lines) with an area over 100,000 mu in Gansu Province was analyzed. The resistance to stripe rust of the cultivars was analyzed. Eleven quantitative traits related to yield of 12 cultivars (lines) Related, Path Analysis. The results showed that spike length, spike weight per plant, grain weight per plant, spike number per spike and grain weight per spike were the main factors contributing to yield. Spike length and number of spikelets per spike should be the main characters of field selection. The article also discussed the breeding ways of stripe rust resistance.
