The Yield and Quality Heterosis of Interspecific Hybrid Between Common Wheat, Spelt Wheat and Club Wheat
普通小麦与斯卑尔脱小麦及密穗小麦种间杂种产量和品质优势标签
-
The heterosis of grain hardness of interspecific hybrid between common wheat and spelt wheat or club wheat were usually negative except that of hybrid between common wheat variety Nongda 3226 and spelt wheat or club wheat.
普通小麦与斯卑尔脱小麦的种间杂种、普通小麦与密穗小麦的种间杂种的籽粒硬度均表现负优势,但农大3226所配的组合的籽粒硬度多为正优势。
-
The average heterosis of the grain yield per plant is 75. 79%, 57. 67% and 12. 55% in the hybrids of the common wheat with spelt wheat, club wheat and itself respectively. the heterosis degree of the interspecific hybrid was greater than that of intervarietal hybrid.
普通小麦与斯卑尔脱小麦的种间杂种每株产量的平均杂种优势为75.79%,普通小麦与密穗小麦的种间杂种每株产量的平均杂种优势为57.67%,普通小麦品种间杂种每株产量的平均杂种优势为12.55%,种间杂种优势大于品种间杂种优势。
-
The heterosis of spike number per plant and grain number of main spike were stable in the intervarietal crosses between years, and so were the grain number of main spike in the crosses of common wheat with club wheat, and were the 1000-grain weight in the crosses of common wheat with spelt wheat.
普通小麦品种间杂种每株穗数优势和主穗粒数优势年度间表现稳定;普通小麦与密穗小麦的种间杂种主穗粒数优势以及普通小麦与斯卑尔脱小麦的种间杂种千粒重优势两年均表现出明显的杂种优势,且幅度相近,其他性状年度间差异较大。
-
The average heterosis of spike number per plant and 1 000-grain-weight were high and obviously related to yield heterosis at 0. 01 and 0. 05 level, respectively; the average yield heterosis of F1 hybrids between common wheat and club wheat was 77. 19%(ranged from-2. 18% to 143. 42%), the average heterosis of spike number per plant and spike grain number were high and both was also obviously related to yield heterosis at 0. 01 level.
结果发现:小麦种间杂种在产量上具有明显的杂种优势,其中斯卑尔脱小麦与普通小麦所配的30个种间杂交组合产量杂种优势平均为109.24%(43.14%~187.96%),单株穗数及千粒重平均优势较大且与产量优势的相关分别达极显著水平和显著水平;密穗小麦与普通小麦所配的30个种间杂种的杂种优势为77.19%(-2.18%~143.42%),单株穗数和主穗粒数优势较大且与产量优势的相关均达极显著水平。
-
The SCA effect was important in the heterosis of the spike number per plant of the intervarietal hybrid, the SCA and GCA were both important in the heterosis of the grain number of main spike of the intervarietal hybrid; the SCA effect played an major role in the heterosis of the spike number per plant of the interspecific crosses of the common wheat and club wheat, the SCA effect played an major role in the heterosis of the 1000-grain weight of the interspecific crosses of the common wheat and spelt wheat.
普通小麦品种间杂种每株穗数杂种优势中,特殊配合力所代表的非加性遗传效应起了主要作用,而主穗粒数杂种优势中一般配合力、特殊配合力所代表的加性、非加性遗传效应所起的作用相当;普通小麦与密穗小麦种间杂种主穗粒数杂种优势中特殊配合力所代表的非加性遗传效应起了主要作用;普通小麦与斯卑尔脱小麦间杂种千粒重杂种优势中特殊配合力所代表的非加性遗传效应起了主要作用。
