Abstract

Tomato production can’t fulfill the consumption needs of tomatoes. One way to fulfill this need is to expand the land by planting tomatoes in the lowlands. However, the limited number of cultivars suitable for planting in the lowlands is an obstacle. Assembling new superior cultivars of tomato plants that have good adaptations in the lowlands is one solution that can be done. The aim of this research was to produce a new tomato strain with superior characters. The research design was using a Completely Randomized Block Design, as a treatment consisting of eight new strains of F6 generation tomato plants, each experimental unit was repeated three times. The variables observed were maximum plant height, number of primary branches per plant, number of fruit bunches per plant, number of fruit per bunch, number of fruit per plant, age of plant beginning to flower, age of fruit starting to form until physiological maturity, fruit diameter, the weight of each fruit, fruit yield per plant, fruit yield per hectare. The data were analyzed for variance, if there was a significant difference between treatments; further tests were carried out with the BNT test at an alpha of 0.05. The results showed that each strain had various quantitative characters. The LA, LA1, and LH strains had a higher potential yield per hectare compared to the other lines. The heritability values in most of the observed quantitative variables have moderate to high values. This shows that the character is more controlled by genetic traits. Keywords: quantitative character, strain, tomato

Abstract

Issues surrounding hybrid corn seeds in Indonesia include the increasing demand for seeds from year to year and the limited selection of hybrid varieties on the market. One solution to reduce the problem of hybrid corn seed availability is to develop new strains or varieties using parent plants from local areas. Polinela corn breeders have currently developed several hybrid corn lines (F1) that need to be tested for performance. The objective of this study was to determine the performance advantages of five Polinela hybrid corn lines compared to five superior commercial hybrid corn varieties developed by several multinational companies. The study was designed using a completely randomized block design (CRBD). The treatments used were five Polinela hybrid corn lines and five commercial hybrid corn varieties. The observations included quantitative yield components and yield potential, as well as several qualitative characteristics of the lines and varieties. The results showed that there were three new hybrid lines, namely line PL 401/PL 20, line PL.401/PL.2020, and line PL 202/PL 40), which had yield potential equivalent to the hybrid varieties BISI 18, NK 22, and Pertiwi 3, with a dry grain yield potential of between 11.7 and 12.9 tons.ha-1. There are three new hybrid corn lines with grain yield potential equivalent to three commercial varieties and higher than two comparison varieties, namely Pioneer 88 and Pertiwi 6.
