Other claims from this paper (13)
- Intervention effect Ur1 increased spikelet number per panicle by 29% in NU relative to N.
- Intervention effect Ur1 increased spikelet number per panicle by 24% in NH relative to N.
- Intervention effect Ur1 decreased panicle number per m2, ripened-grain percentage and 1000-grain weight by 4 to 8% and 4 to 6% in NU and NH.
- Association Analysis of variance indicated that Ur1, genetic background and their interaction had significant effects on yield.
- Observation The five Ur1-carrying isogenic lines had yields from 752 g/m2 (NU) to 542 g/m2 (30U).
- Intervention effect Ur1 increased yield by 250 g/m2 (61%) to 75 g/m2 (16%) relative to N in field conditions.
- Intervention effect Ur1 increased spikelet number per panicle by 62.1 to 39.2 (90% to 42%) relative to N in field conditions.
- Intervention effect The spikelet-increasing effect of Ur1 was greater on a small-panicled genetic background than on a large-panicled genetic background.
- Intervention effect Ur1 decreased ripened-grain percentage by 17% in 30U relative to 30+.
- Association Ur1 increased culm length in 27U, 52U and 74U.
- Association No increase in culm length was seen in NU and 30U with Ur1.
- Observation Yield of NU, NH and N was in the order NU > NH > N, with no significant difference between NU and NH.
- Recommendation NU could be a prospective material for developing high-yielding japonica varieties carrying Ur1, given lodging tolerance and yield.
