The male parent of the MATAG hybrid, Tagnanan, is an allogamous tall type, with substantial variation thus, contributing to the possible inconsistency in MATAG hybrid production and consequently lowering the efficiency of genuine MATAG production. Therefore, the selection and improvement of homogeneous Tagnanan individuals as pollen sources must be made to ensure the production of high-quality MATAG. This study aimed to describe the variation and evaluate the Tagnanan population currently utilized as the main pollen source for MATAG production based on fruit yield and quality components. A quantitative descriptive study of the growth and coconut yield attributes was done on the 13-year-old Tagnanan population at DOA Teluk Bharu, Perak. The results revealed that fruits come in three colors: gold, green, and reddish-orange. Furthermore, the morphological appearance of fruits varies in the polar and equatorial view shapes of fruits, with round polar and equatorial view forms of fruits recording the largest number of fruits compared to the other view shapes of fruits. The weight of fruits showed substantial variance in descriptive statistics and PCA, and descriptive statics analysis suggests that shell thickness is one of the fruit attributes with the lowest variation. The low variation and no significant parameters are the parameters that can be taken into consideration for future decisions in producing good quality MATAG seed production regardless of the color of the fruits.

Abstract

The male parent of the MATAG hybrid, Tagnanan, is an allogamous tall type, with substantial variation thus, contributing to the possible inconsistency in MATAG hybrid production and consequently lowering the efficiency of genuine MATAG production. Therefore, the selection and improvement of homogeneous Tagnanan individuals as pollen sources must be made to ensure the production of high-quality MATAG. This study aimed to describe the variation and evaluate the Tagnanan population currently utilized as the main pollen source for MATAG production based on fruit yield and quality components. A quantitative descriptive study of the growth and coconut yield attributes was done on the 13-year-old Tagnanan population at DOA Teluk Bharu, Perak. The results revealed that fruits come in three colors: gold, green, and reddish-orange. Furthermore, the morphological appearance of fruits varies in the polar and equatorial view shapes of fruits, with round polar and equatorial view forms of fruits recording the largest number of fruits compared to the other view shapes of fruits. The weight of fruits showed substantial variance in descriptive statistics and PCA, and descriptive statics analysis suggests that shell thickness is one of the fruit attributes with the lowest variation. The low variation and no significant parameters are the parameters that can be taken into consideration for future decisions in producing good quality MATAG seed production regardless of the color of the fruits.
