Breeding system of fruit set in black pepper (Piper nigrum L.)

Pooja S, Dr. Sreekala GS and Vijaykumar B Narayanapur
The research project “Agents of pollination and breeding system on fruit set of Piper nigrum L. was carried out in the Department of Plantation Crops and Spices, College of Agriculture, Vellayani, Thiruvanthapuram during 2017-2019. The different types of breeding system investigated in black pepper were open pollination, autogamy, Geitonogamy, Xenogamy and apomixes. Treatment, B5 were on par with B4, B3, B2, B1 and were significantly superior compared to other treatments. The percentage of fruit set of treatment B7 (83.97), B8 (82.85), and B10 (89.15). No fruit set were observed in treatment, B9. Thus, in black pepper open pollination, autogamy and geitonogamy equivalently contributed to fruit set while the fruit set due to xenogamy was less compared to the open pollination, autogamy and geitonogamy breeding system. However, apomixis was not noticed. A basic study of floral structure and phenology was essential to understand the pollination systems of Piper nigrum L. Predominant form of breeding system in black pepper was gietinogmy and autogamy. However, apomixis could not be proved from the experiment.
