Non-grain parameters like height, flowering and maturity should also be tried to break yield plateau in wheat. This study explores such possibilities by analysing performance of released and pre-released varieties evaluated in ten diverse production environments of India during the period 2000-2020. Regression analysis supports relevance of such non-grain determinants in grain yield under every environment but magnitude of impact can vary. Collective contribution of non-grain parameters can be high in a production environment where growth condition is most favourable for wheat growth and every factor is important in such situations. They contribute less in the environments engrossed with abiotic stress and merely one or two factors can be earmarked for selection. Besides yield, this selection strategy can also enhance grain weight in certain environments. At a time when selection for grain attributes is not providing further push; it would be worth trying to explore these non-grain field indicators as selection strategy for further advancement in productivity and grain weight of bread wheat.

可以在不同的生产环境中引导作物物候和株高来提高小麦的生产力吗？

还应尝试使用非谷物参数，例如高度，开花和成熟度，以打破小麦的产量平稳期。这项研究通过分析在2000年至2020年期间在印度十个不同生产环境中评估的已发布和预发布品种的性能来探索这种可能性。回归分析支持在每种环境下此类非谷物决定因素与谷物产量的相关性，但影响的大小可能会有所不同。在生长条件最有利于小麦生长的生产环境中，非谷物参数的集体贡献可能很高，而在这种情况下，每个因素都很重要。在充满非生物胁迫的环境中，它们的贡献较小，只能指定一个或两个因素进行选择。除了产量 这种选择策略还可以在某些环境中增加谷物的重量。在对谷物属性的选择不再提供进一步推动的时候；值得尝试探索这些非粮食领域指标，作为进一步提高面包小麦生产力和粒重的选择策略。
