Abstract:
Astudy was conducted in the College of Horticulture, Kerala Agricultural University, Trichur during the year 1977–78 find the extent of variation in vegetative, flowering, apple, and yield characters of 100 seedling progenies derived from open pollimated single mother tree (T - 20). The objective of the study was to assess the suitability or otherwise of selecting seeds from a single high yielding type for propagation.
Considerable variation was observed in vigour of trees expressed as height, spread and number of primary branches in both the years.
Girth was the least variable attribute.
Flowering also varied considerably between the ibdividuals.
Qualitative characters of apples similarly varied to a considerable extent.
Yield of nuts during both the years was also highly variable.
The fact that inspite of single tree selection, more than 50 per cent of trees yielded below the mean suggest that greater caution has to be exercised while realising seeds of selected types as high yielders.
Vegetative propagation is perhaps the only assurance for the transmission of characters from mother tree to their progenies.
