This research was conducted in Shikan locality, North Kordofan, Sudan during 2018/2019. The aim of this research is to identify phenotypic characteristics and producers’ perceptions on high gum yield hashab trees (Acacia senegal L.). It also aims to scrutinize growth attributes of high yielding hashab tree in the study area. Social survey was done where interview was conducted using structured questionnaire which distributed to seventy seven owners of high gum yield hashab trees. Qualitative data such as bark color, flowering and fruiting period were also collected. Descriptive Statistical Analysis in Statistical Packages for Social Sciences (SPSS version 16.00) where mean, percentages, and counts were calculated. Moreover, correlation analysis was done. The results revealed that age of high gum yield hashab trees ranged from 5 to 17 years. According to the most of respondents (90%), high gum yield hashab trees exudates gum firstly at age of 5 years as a minimum while 78% of respondents stated that the bark color is reddish at tapping position. The majority (93%) of respondents described shape of gum nodules as round. As phenotypic characteristics of high gum yield hashab trees, beginning of flowering and fruiting period is May to August where positive correlation (0.32) was found. Positive correlation (0.24) was also found between starting gum exudation and number of pickings/season. The study concluded that high gum yield hashab trees could be phenotypically identified and also through experience since tree form, color, flowering and fruiting are always under farmers focus. The study recommends investigating relation between phenotypic characteristics and genetic sources of high gum yield hashab trees.
