Abstract
ABSTRACT Depending on altitude, capsules were considered mature and were reaped after five to seven months from anthesis, at which time they had begun to turn brown. Out of 18 clones which were tested, 12 set varying amounts of parthenocarpic fruit. By sieving seed and chaff and discarding all particles passing through a sieve of gauge 500 urn, 84% of the viable seed was retained; this fraction was the best as regards initial vigour and survival, and percentage purity was improved. Out of 45 clones which were self-pollinated, 44 yielded some seed. Fifteen types of abnormality were recognized among the progeny and ten of these were classed as detrimental. Four of these deviant types were used as markers in assessing percentage of selfing, which varied from 10% to 38%, except in one test of out-of-season flowering, for which a figure of 83% was obtained. Apart from abnormal progeny and reduced seed yield after selfing, the most consistent inbreeding effect was on height; bole straightness was also adversely...
