Improving Selection Efficiency at the Head Rows Stage of Winter Wheat Breeding by Using the Normalized Difference Vegetation Index

Q: What does this research mean for the field?

Using the Normalized Difference Vegetation Index (NDVI) at early growth stages strongly correlates with grain yield and can improve selection efficiency compared to traditional visual selection in winter wheat breeding. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To compare conventional breeder visual selection against normalized difference vegetation index (NDVI) selection at the head rows stage in winter wheat breeding programs.
Evaluated 1,246 head rows (HRs) across 38 winter wheat populations using breeder visual selection, high NDVI selection (NDVI+), and low NDVI selection (NDVI-).
Measured NDVI at the pre-heading stage in HRs and at early grain filling in Preliminary Yield Trials (PYTs) to assess correlations with final grain yield.
Selected 403 out of 1,246 HRs across protocols: 13.2% by visual selection, 10.0% by NDVI+, 3.0% by NDVI-, and 6.1% jointly by visual selection and NDVI+.
NDVI correlated positively and significantly with grain yield at the pre-heading stage in HRs (r = 0.55, p < 0.01) and during early grain filling in PYTs (r = 0.73, p < 0.01).
