Other claims from this paper (13)
- Intervention effect At 4 kg, Betzes seed set was 18% after five-leaf application.
- Intervention effect At 4 kg, two-row Unitan seed set was 33% after six-leaf application.
- Intervention effect At 4 kg, six-row Unitan seed set was 29% after six-leaf application.
- Intervention effect Four kilograms of RH-531 caused 40% female sterility.
- Observation Female sterility was greatest after six-leaf treatment, especially in Unitan six-row.
- Intervention effect Increasing RH-531 rates reduced yield, height and flowers per spike.
- Intervention effect Increasing RH-531 rates reduced lodging, kernel size and spike length.
- Association Yield and grain protein were negatively correlated.
- Observation Grain protein per hectare was lower in 4 kg/ha plots because of lower yield.
- Intervention effect Six-leaf spraying reduced yield more than five-leaf spraying.
- Observation Treatment affected Unitan six-row growth traits less than those of the other cultivars.
- Intervention effect In Unitan isolines, six-leaf treatment reduced flowers per spike less than five-leaf treatment.
- Recommendation The authors conclude RH-531 did not induce enough male sterility for hybrid production and caused drastic side effects.
