Description Global assessments elucidate the expected significant effect of climate change
on future agriculture. In black pepper also, change in weather parameters plays
an important role in its productivity. The present study attempts to make an
assessment of the impact of genotypes and environment on sex fonn in black pepper. The observation on the flower composition of pepper varieties in different regions, revealed that there exists considerable extent of variability among genotypes and is "highly influenced by the weather arameters. High percentage of bisexual flowers is essential for pollination and fruit set. For
Panniyur-l, a popular variety, high altitudes and heavily shaded conditions
cause the proportion of female flowers to be higher compared to hermaphrodite
flowers. In contrast, the shift towards femaleness was not much pronounced in
a few of the local cultivars such as Karimunda, Thevanmundi, Chumula and Neelamundi under similar conditions. Light availability, temperature and rainfall are found to be the major factors influencing the flower composition which in turn determine the productivity. The shift towards femaleness and lack of pollination are one of the major reasons for spike shedding among popular varieties such as Panniyur-l in high altitudes.
