Other claims from this paper (14)
- Observation Genotypes G90, EC2, PS6 and PS7 were identified as high earliness index stress tolerant.
- Observation Crosses G86 x G75 and G90x G75 showed moderate late-planting stress tolerance.
- Observation Crosses G80 x PS7 and G80 x G83 showed moderate late-planting stress tolerance.
- Observation The moderately tolerant crosses showed the highest yield potential at the later planting date.
- Observation Crosses EC1 x PS6, G90 x PS7 and EC2 x PS6 were earlier, with the highest earliness index.
- Observation Crosses EC2 x G83 and G80 x PS6 were earlier, with the highest earliness index.
- Observation General combining ability variance was larger than specific combining ability variance only for first fruiting node and days to first flower and first boll under late planting.
- Observation For the remaining traits, specific combining ability variance was greater than general combining ability variance.
- Observation Additive and non-additive variation was significant for the traits expressed.
- Observation Degrees of dominance indicated partial dominance for all studied traits.
- Observation Broad-sense heritability was greater than narrow-sense heritability for all traits.
- Recommendation Lines EC1, EC2 and PS6 and their descendants can be used as a breeding nucleus for genotypes planted up to early May.
- Recommendation LP-tolerant genotypes should have a low "s" index and be shorter than current genotypes, with low first sympodial node, early boll set and high earliness index.
- Recommendation Backcrossing with selected genotypes followed by repeated selfing is a successful breeding strategy for late-planting tolerance.
