Title

N. L. INNES Annals of Applied Biology 1974. doi:10.1111/j.1744-7348.1974.tb01489.x
Other claims from this paper (9)
- Observation Leaf inoculation of cotton lines with the blight pathogen was successful.
- Observation Stem inoculation of cotton lines was only partially successful.
- Observation Boll inoculation with two techniques failed to produce measurable disease symptoms.
- Association Leaf resistance and stem resistance to bacterial blight were generally well related.
- Observation Strong resistance conferred by B2B9K was confirmed, as effective as B2B6 or B2B3B6.
- Observation No other B-gene combination was as effective when inoculated artificially.
- Observation In natural field attack, only mild symptoms were found in lines homozygous for B1B9K and for B4B6.
- Observation Under natural field attack, lines with B2B6 showed no symptoms.
- Observation Under natural field attack, lines with B2B3 were severely attacked.
