Abstract
This study purpose to genetically engineer local cayenne pepper through breeding with multigamma irradiation methods to obtain superior offspring that adapt to drought stress, extreme weather, pest tolerance, and high production. The method used consists of observation, sampling, irradiation, careful selection, purification, comparative, and interpretation. The brief procedure of the study included: observations for taking samples, inventorying the physical characteristics of local chili parent varieties, selecting research sites, cultivating the planting area, irradiating the sample at a dose of 2500 rads for 30 minutes, soaking the planting area, planting seeds, irrigation, observing the age and ability to grow seeds, doing embroidery, weeding and fertilizing, observing the condition of plants during growth, harvesting, weighing the mass of fruit per tree, analyzing several nutritional content, comparing the physical and chemical characteristics of the parent varieties and selected superior offspring, and interpreting. Result of research: Local cayenne pepper of superior selected offspring as a result of multigamma irradiation can adapt to drought conditions, extreme weather, tolerant of pests and diseases, and significantly increase production compared to the parent variety. The average production of the selected superior offspring was 11.11 t ha-1, while the parent variety was 6.54 t ha-1 with a percentage increase in the production of local cayenne pepper from the selected superior offspring was 41.13%.
Highlights
1.1 The Problem and Purpose of ResearchThe main problem investigated in this work was genetic engineering of local cayenne pepper through breeding to use multigamma irradiation
The purpose of this research is genetic engineering of local cayenne pepper through breeding with multigamma irradiation method to obtain superior offspring that can adapt to less water and extreme weather, tolerant of pests and diseases, and high production
The results obtained based on observation, measurement, and calculation data show the physical characteristics of local cayenne pepper varieties of parent and offspring developed through breeding using multigamma irradiation methods and careful selection to obtain superior offspring that can adapt to drought conditions, extreme climate, pest-disease tolerance, and high production
Summary
The main problem investigated in this work was genetic engineering of local cayenne pepper through breeding to use multigamma irradiation. The purpose of this research is genetic engineering of local cayenne pepper through breeding with multigamma irradiation method to obtain superior offspring that can adapt to less water and extreme weather, tolerant of pests and diseases, and high production. Cayenne pepper belongs to the eggplant family (Solanaceae) originating from Peru, the American continent which spread throughout America, Europe, Africa, and Asia. In the 16th century, Portuguese and Spanish traders introduced chili originating from South America to Asia and Africa through trade routes (Law et al, 2015; Assagaf, 2017). Carotenoids, capsantin and capsaicin which give a spicy taste
