Other claims from this paper (11)
- Observation Tropical landraces were more promising for aboveground biomass yield under irrigation and rain-fed conditions.
- Association Drought performance depended on green leaf area retention, with r of -0.47.
- Association Drought performance was positively associated with plant height, with r of 0.50.
- Association Drought performance was positively associated with maturity, with r of 0.61.
- Observation SDS 1948-3 was identified as stay-green and IS 33350 as senescent.
- Observation Stay-green inheritance in the cross progeny appeared polygenic with a dominant major gene reducing senescence rate.
- Association Stay-green genotypes had high leaf nitrogen content.
- Method / resource A linkage map with nine groups and 40 SSR loci spanned 439 cM.
- Observation Mean distance between adjacent loci in the map was 15 cM.
- Observation Three chromosomal regions were tentatively located as related to delayed senescence.
- Recommendation The authors suggested SDS 1948-3 could contribute to drought-tolerant, high biomass breeding.
