Highlights • Linear and consistent grain yield genetic gains in the HRWYT has been observed.• Several best performing lines were common in both high and low rainfall environments.• The genetic gains were explained by paralleled increases in grain weight, day to maturity and grain filling period.• These results indicate continuous genetic progress and yield stability in the HRWYT germplasm developed by CIMMYT.

CIMMYT 高降雨量小麦筛选苗圃的谷物产量遗传增益和生理相关性状的变化在国际环境中进行了测试


亮点 • 在 HRWYT 中观察到了线性且一致的谷物产量遗传增益。• 在高降雨量和低降雨量环境中都常见一些表现最好的品系。• 遗传增益是通过籽粒重量、成熟天数和籽粒灌浆的平行增加来解释的• 这些结果表明CIMMYT 开发的HRWYT 种质资源具有持续的遗传进步和产量稳定性。
