| 摘 要： | 以10个小麦品种(系)为材料,对株高与穗部性状间进行了相关分析及穗粒数的改良途径分析,结果表明:穗粒数与株高呈负相关,而与穗长、分化小穗、结实小穗和小穗结实率均呈显著或极显著的正相关;穗长和小穗结实率对小麦粒数的影响最大,均为极显著正相关;小麦穗粒数的改良过程中,应在培育矮秆、大穗的基础上最大限度地提高小穗的结实率。

| Abstract: | A study was carried out on spike- section characterisitics by correlation and partial correlation in wheat genotypes. The results showed negative correlation between plant height and kernel number per spike, but significant or highly significant correlations between kernel number per spike and spike length, total spikelets, fertile spikelets and setting percentage; The action of spike length and setting percentage of spikelet was most important on kernel number per spike with the highly significant standardized estimate; The result indicated that reform the kernel number per spike should be focused on nurturing short plant, large spike and increasing the setting percentage of spikelet. |
