Undergraduate Thesis. Bachelor of Science in Agriculture Major in Crop Science, Cavite State University, Indang, Cavite. April 2015. Adviser: Analita dM. Magsino, PhD This study generally aimed to evaluate the fruit variability of sugar palm or kaong (Arenga pinnata) in upland Cavite, Philippines. Specifically, it aimed to determine the fruit characters of sugar palm; evaluate the correlation among the various fruit characters of sugar palm and select fruit characters which are relevant in the future selection and improvement works in sugar palm. Eleven fruit characters of 25 sugar palm accessions from Indang, Bailen, Magallanes, Amadeo and Mendez were measured and counted. The variability in all characters was determined using the Shannon-Weaver Diversity Index. Correlation coefficients of selected character combination were computed following PROC CORR (SAS System, 1985) Wide variability was found in fruit weight, fruit length, fruit width, number of fruits per cluster, length of the cluster, aborted fruit per cluster, nut/meat yield and edible portion. Conversely, narrow variability was found in the number of nuts per fruit and fruit shape. Correlations of the majority of fruit character combinations were highly significant. Fruit weight and fruit length, fruit weight and fruit width, fruit length and fruit width, and nut/meat yield and edible portion were highly correlated. Number of fruits per cluster and percent aborted fruit per cluster were also highly but negatively correlated. Moderately positive correlations were found in the number of fruits per cluster and length of the cluster and fruit shape and number of nuts per fruit. Weak positive correlations were found in fruit weight and number of nuts per fruit, fruit length and number of nuts per fruit, fruit width and number of nuts per fruit, fruit shape and fruit weight, fruit shape and fruit length, and fruit shape and fruit width. Length of the cluster and percent aborted fruit per cluster had no significant correlation. The wide variability in fruit characters existing in the natural population of sugar palm in upland Cavite can be exploited in selection and breeding programs. In particular, length of the cluster, fruit weight, and nut yield are the important characters for handling and evaluation of as many sugar palm genotypes as possible.

This study generally aimed to evaluate the fruit variability of sugar palm or kaong (Arenga pinnata) in upland Cavite, Philippines. Specifically, it aimed to determine the fruit characters of sugar palm; evaluate the correlation among the various fruit characters of sugar palm and select fruit characters which are relevant in the future selection and improvement works in sugar palm.

Eleven fruit characters of 25 sugar palm accessions from Indang, Bailen, Magallanes, Amadeo and Mendez were measured and counted. The variability in all characters was determined using the Shannon-Weaver Diversity Index. Correlation coefficients of selected character combination were computed following PROC CORR (SAS System, 1985) Wide variability was found in fruit weight, fruit length, fruit width, number of fruits per cluster, length of the cluster, aborted fruit per cluster, nut/meat yield and edible portion. Conversely, narrow variability was found in the number of nuts per fruit and fruit shape.

Correlations of the majority of fruit character combinations were highly significant. Fruit weight and fruit length, fruit weight and fruit width, fruit length and fruit width, and nut/meat yield and edible portion were highly correlated. Number of fruits per cluster and percent aborted fruit per cluster were also highly but negatively correlated. Moderately positive correlations were found in the number of fruits per cluster and length of the cluster and fruit shape and number of nuts per fruit. Weak positive correlations were found in fruit weight and number of nuts per fruit, fruit length and number of nuts per fruit, fruit width and number of nuts per fruit, fruit shape and fruit weight, fruit shape and fruit length, and fruit shape and fruit width. Length of the cluster and percent aborted fruit per cluster had no significant correlation.

The wide variability in fruit characters existing in the natural population of sugar palm in upland Cavite can be exploited in selection and breeding programs. In particular, length of the cluster, fruit weight, and nut yield are the important characters for handling and evaluation of as many sugar palm genotypes as possible.
