Forty tomato genotypes were evaluated in Randomized Block Design with three replications at College of Agriculture, Vellayani, Kerala, during October 2014 to April 2015. Wide range of variability was observed among the characters studied for effective selection of superior genotypes suited which have a great interest for polyhouse tomato breeding. The present appraisal uncovered that PCV and GCV were higher for plant height, truss per plant, fruit weight, fruits per truss, fruits per plant and yield per plant which suggested greater variability among the accessions and sensitiveness of the attributes for making further improvement by selection. High heritability was observed for plant height, pollen viability, truss per plant, fruit weight, fruit girth, fruits per truss, fruits per plant, lycopene and yield per plant.Keywords
Tomato, Variability, Heritability, Genetic Advance.

A study was conducted in a yard long bean (Vigna unguiculata sup/ssp. sesquipedalis) hybrid VS 50 (Kakkamoola Local) x VS 26 (Vellayani Jyothika) to assess the percentage fruit set at two time intervals and to identify the best time interval for pollination in yard long bean hybrids. Hand pollination was done using VS 50 as female parent and VS 26 as male parent for seven consecutive days at two time intervals, 6.30 – 7.30 am and 7.30 – 8.30 am. Higher percentage of fruit set (36.8 %) was observed between 6:30 – 7:30 a.m. as compared to the time interval 7:30 – 8:30 am. (23.8%). Pollen viability was determined for the parents VS 50 (Kakkamoola Local) and VS 26 (Vellayani Jyothika) at 6.30, 7.30 and 8.30 am. Highest pollen viability for both the parents VS 50 and VS 26 was observed during 7.30 am. The present study shows that the best time interval for crossing in yard long bean is 6.30- 7.30 a.m.Keywords
