“…The desirable characteristics of deciduous fruit with normal esh include the fact that they are less prone to falling in light winds or being touched, and they also do not develop mould during drying. According to Werner and Honma (1980), easy fruit removal was positively correlated with fruit length, diameter, and weight, and fruit detachment force was inherited. (Villalon and Bryan, 1970) Pepper fruit do not have an abscission layer in their pedicels as do tomatoes, and their pedicel attachments are quite strong in cultivars with large fruits.…”

Mutation breeding experiment was initiated during 2012-13 with an objective of inducing variability in ‘GPM00-120-S-1’ (Byadgi Dabbi segment a popular chilli cultivar in Karnataka, India) an advanced breeding line. In 0.4 per cent of EMS treated M3 population, a plant with soft and deciduous fruit character was identified and selfed seeds were used to grow a larger number of plants in M4 generation. Two kinds of plants were observed in M4 generation viz., soft flesh (named as non persistent calyx , NPC-4) and normal flesh (normal flesh with erect type named as NPC-3 and normal flesh with pendent type named as NPC-5) with deciduous fruits. All the three putative mutants were selected and further advanced by pure line selection method until they reach the homozygosity. The homozygous lines were then evaluated for yield, quality and response to incidence of pest and diseases along with check variety for four years from 2017-2021. Molecular characterization was also done using SSR marker. The lines exhibited stability for the trait of deciduous fruits and high yield over the seasons and over the checks. The newly developed stalk less chilli varieties with novel traits may not only reduces the cost of harvest crop but also improves the quality of the chilli powder and other products.

Delayed or extended fruit abscission in many cultivars of macadamia, Macadamia integrifolia (Proteaceae), necessitates multiple harvests from the orchard floor. However, it is not known whether there is a link between fruit maturation and timing of abscission. In this study, relationships between kernel oil content, nut size, removal force and abscission were investigated in 2 commercial orchards, one in Queensland (24˚S) and one in New South Wales (29˚S). Abscission lasted 6 months (March–September) at both sites due to differences in timing of abscission between cultivars and extended abscission within cultivars. Abscission was consistently associated with declines in fruit removal force, from more than 2 kgf in early March towards 1 kgf at the peak of abscission. Later abscission in cvv. A16 and 246, compared with cvv. 344 and 741, was correlated with more gradual declines in removal force. Fruits containing small nuts and kernels tended to possess lower removal forces and these fruits were often heavily represented in the population of fruits that abscised earliest. There was little or no difference in kernel oil content between fruits of different removal force or between sample dates for any cultivar, either for samples taken from the tree or from the orchard floor. Attainment of maximal oil content and onset of fruit abscission are therefore independent processes in macadamia. If abscission can be accelerated, it may be possible to advance the harvest of late-abscising cultivars such as A16 and 246 which retain mature nuts on the tree up to several months after maximal oil accumulation.
