- In the study , six different ecotype varieties of common wheat and f1 derived from 6 6 complete diallel crossing system were selected for the research on the characteristics and heterosis of spike differentiation . the results showed that heterosis existed in most key spike differentiation phases and varied with different ecotype varieties . heterosis of spike differentiation was positively correlated with heterosis of hybrid yield . finally , the author concluded that it was the best way to produce strong heterosis combination by selecting the mode of “ spring wheat winter wheat ” in huanghuai winter wheat region
对6个不同生态类型小麦品种及其完全双列杂交f1幼穗分化特点和穗分化杂种优势的研究表明,杂种幼穗分化各主要时期普遍存在杂种优势;不同生态类型组配方式的杂种穗分化优势不同;穗分化杂种优势与产量杂种优势具有一定相关关系;黄淮麦区杂交小麦最佳生态组配方式为春性品种冬性品种。 - The study on the characteristics of development and seed setting of different spikelet and floret positions was important for the realization of big - spike - cultural - goal with more spikelets and grains . with both the winter type ( wv ) and spring type ( sv ) varieties sown at different dates , it was found that the greater seed setting capacity of spikelets resulted in more grain number of spike . the trend of differences in grain weight per spikelet between the different sowing dates and varieties was similar to that of grain number . the correlation between the average grain weight of middle spikelets and lower spikelets and the grain weight per spike was highly significant . the environmental changes resulted from different sowing dates mainly effected the middle spikelets development , even though the differences between wv and sv were represented in every spikelet positions . the grain weight on the second floret position was most sensitive to the development status of wheat plant and environmental changes , and could represent the yielid potential of the whole spikelet . the results showed that the enhancement of seed setting of the middle spikelets ( from 5th to 15th ) and the grain development from the first to third floret positions was a key to realize big - spike and grain
确定小麦不同小穗位和小花位发育与结实特性是实现大穗多粒的重要前提.本文通过对冬、春性小麦品种分期播种试验得出,较高的小穗结实力是增加穗粒数的重要因素.不同播期、品种之间,小穗粒重和粒数呈现相同的变化趋势.中部以及基部小穗粒重与穗粒重之间呈高度正相关.体现环境差异的播期效应以对中部小穗发育的影响为主,而冬、春性品种的基因型差异可反映在各个小穗位上.第2小花位的子粒发育状况反映整个小穗的生产能力.结果表明,促进中部优势小穗(第5 15小穗)结实和第1 3小花位子粒发育是提高小花结实率和穗粒重的关键 - The winter tiller is more than the spring tiller at quantity hi leymus chinensis , calamagrostis epigeios and c . rigidula population at the beginning growing season . it is an efficient strategy to increasing survival fitness and propagating potential for rhizome grass to grow many active and strong winter tillers
生长季初期,羊草、拂子茅和硬拂子茅种群返青的分蘖株以冬性植株多于春性植株,冬性植株生活力旺盛、抗性强,形成冬性植株是根茎型禾草种群提高生存适合度,增强营养繁殖力的有效策略。
