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。

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.

结果表明：不同黄瓜品种直接不定芽数量诱导存在显著差异，但长度诱导无显著差异；6-苄氨基嘌呤对直接不定芽数量和长度的诱导作用显著，其中4.0mg/L为数量诱导适宜浓度，其出芽率和每外植体出芽数达到最高，分别为100.0%和11.1，0.5mg/L为长度诱导适宜浓度，其平均芽长12.0mm；外植体的大小对直接不定芽数量和长度均具显著影响，随着子叶的增大诱导直接不定芽的数量和长度增加，其中单片完整子叶为最适宜大小，其出芽率、每外植体出芽数和平均芽长分别达到100%、6.7和17.1mm；硝酸银也对直接不定芽数量诱导影响显著，其中2.0mg/L为适宜浓度，出芽率和每外植体出芽数分别达到97.2%和4.2，但对芽长有抑制作用。
