从种植在多种环境中的一大批粒用高粱杂交种里,挑选出三个稳定(适应性良好)的基因型(Funks G623GBR、Na+162、NC+172)和三个不稳定(仅适应优良环境条件)的基因型(ACCO X9299、先锋8674、RS626),试图用它们说明这两类杂交种产量因素的作用及对环境胁迫的反应。14个地点的产量均值变化范围为5400—9800公斤/公顷。全部基因型随着环境的改善都产生更多的穗数/米~2和粒数/穗,从而提供更
Three robust (well-adapted) genotypes (Funks G623GBR, Na + 162, NC + 172) and three instability (adapts only) were selected from a large number of grain sorghum hybrids grown in a variety of environments Good environmental conditions) (ACCO X9299, Pioneer 8674, RS626) were used to illustrate the effects of these two types of hybrids on yield factors and their responses to environmental stress. The average yield of 14 locations varies from 5400 to 9800 kg / ha. All genotypes produced more spikelets / m 2 and grain number / spike as the environment improved, thus providing more
