Qualitative and Tomato

Hence the present investigation carried out for genetic variability for quantitative and qualitative traits in genotypes of tomato. The knowledge of genotypic and phenotypic coefficient of variation is being useful in designing selection criteria from variable population. In general, it was noted that the value of phenotypic coefficient of variation is higher than the genotypic Coefficient of Variation For all the traits.

Correlation and path analysis were carried out in twenty eight tomato genotypes for quantitative and qualitative characters. The association studies showed that fruit yield per plant was genotypic and phenotypic positive correlated with number of flowers per plant, number of fruits per cluster, fruit diameter, fruit length, average fruit weight, number of locules per fruit and seed yield per plant.

The effectiveness of the bumble bee Bombus haemorrhoidalis Smith (Hymenoptera: Apidae) was evaluated and compared to non-bumble bee pollinated tomato (Solanum lycopersicum) crop grown under protected conditions. Some qualitative and quantitative characteristics such as day to first fruit harvest, number of fruits, fruit size, in treatments with or without bumble bee colony were recorded. Results based on measurements of mentioned parameters showed highly significant difference.

Twenty four tomato genotypes were evaluated during June to September 2018 at Horticulture College and Research Institute, Periyakulam with an aid to estimate genetic diversity for 15 quantitative and qualitative characters. Using Mahalanobis D2 statistics method, the 24 genotypes were grouped into three clusters, indicating the presence of diversity among the genotypes for different traits. The cluster III containing 17 genotypes followed by cluster II and I comprises of four and three genotypes respectively (Table 5). The highest intra-cluster distance was recorded in cluster III (60.

Tomato (Solanum lycopersicum L.) is one of the most important vegetable crops under solanaceous group which can be grown both under open field conditions and greenhouses. Tomato has achieved high popularity especially in the recent years because of lycopene’s anti-oxidative activities and anti-cancerous functions. The cultivated tomato has been used in genetic studies because of the ease with which it can be easily manipulated and also its diversity present within the population.

Line x Tester analysis was performed by employing fourteen tomato genotypes (10 lines and 4 testers) to develop 40 hybrids. These hybrids along with parental lines and commercial check Naveen 2000+ were evaluated to know the extent of heterosis exhibited to different yield and yield attributing traits. Results revealed that nine hybrid combinations produced significantly increased heterotic effect over the better parent.
