摘要: 本研究以川农单交9号和农大65为供试材料,探讨了川农单交9号在11个播种期中的产量和农艺性状变异,确定了川农单交9号从3月28日起到5月27日都是它的适宜播期,6月6日以后亦可播种,农大65的适宜播期是3月28日至5月17日,5月27日后不宜播种。川农单交9号比农大65在不同播期中表现高产稳产,是因它农艺性状在各时期的变异小,稳定性高。

Abstract: This prper deals wth the study of suitable sowing times of two maize single crosses. SAU 9 and BAU 65. The variances of yields and other traits of these two hybrids over eleven sowing dates were compared. It was concluded that SAU 9 suits for spring, summer and autumn sowing, but BAU 65 suits for spring and early summer sowing only. The optimal sowing times of SAU 9 and BAU 6.5 are from 28th of march to 27th of may and from 28th of march to 17th of may, respectively. The comparison also exhibits that SAU 9 has a higher and more stable yield than BAU 65 due to its lower variability and higher stability.
