Spectral Water Indices for Assessing Yield in Elite Bread Wheat Genotypes under Well‐Irrigated, Water‐Stressed, and High‐Temperature Conditions

The objective of the present work was to determine the relationship between spectral reflectance indices (SRI) and yield in spring wheat ( Triticum aestivum L.) in NW Mexico in three environments (irrigated, water‐stress, and high‐temperature). The SRI were classified into vegetative indices (three indices) and water indices (five indices). The SRI were determined at booting, heading, and grain‐filling in advanced lines of three trials of the...
