Selection of tomato breeding lines based on morphological traits associated with high yield potential in double-cross population

Abstract. Anisa WN, Afifah EN, Murti RH. 2022. Selection of tomato breeding lines based on morphological traits associated with high yield potential in double-cross population. Biodiversitas 23: 2973-2980. Low production is a global problem. Plant has been intensified to develop high-yield varieties and meet the vegetable crops. an essential part plant evaluate desirable lines. This study aimed identify from 13 2 commercial tomatoes. Collected data were analyzed using analysis variance, post hoc, path, principal component analysis. Results showed that 9 lines, namely, BV-1, BV-2, BV-3, BV-6, BV-7, BV-9, BV-11, BV-12, BV-13 had number fruits per fruit weight. Given their path coefficient value significant correlation (P<0.05) potential, these two characteristics are highly recommended be used as selection criteria for plants. The following heritability: weight, length, diameter, firmness, locules, pericarp thickness, total soluble solid, flowers bunch, plant, harvesting age.
