FIELD SCREENING OF TOMATO GERMPLASM FOR THE MORPHO-PHYSIOLOGICAL TRAITS IN AUGMENTED BLOCK DESIGN

Abstract

A field experiment was conducted to assess the performance of tomato germplasm for different morpho-physiological traits in field condition. Seventy-five tomato genotypes (local and exotic) were transplanted in field following augmented complete block design. There were 5 blocks each having 12 genotypes along with three checks i.e., Rio Grande, Roma, Pakit. Data was recorded for plant height, days to flowering, days to maturity, number of flowers per inflorescence, number of inflorescence/plants, Fruit set/ inflorescence, chlorophyll content, yield per plant. For yield/plant trait, ten genotypes have the greater value than these three check genotypes adjusted value in which genotype GSL-198 (1772.78) and LA-1969 (138.11) having greater value and the genotypes 19912 (409.08) and 10165 (470.11) are with less adjusted value than the checks. Maximum number of yields per plant were observed in genotype GSL-198(1782g) and minimum were observed in genotype 19912 (400g).   Genotype 17903, 17869 were high yielding while genotype 17903 were recommended for days to maturity, number of flowers per inflorescence.
