Genetic variability and heri lability parameters were studied in48snakegourd accessions. The genotypic coefficient of variation was high for f r u i t i ng nodes on main vine, male flowers/plant, sex ratio, fruits/plant and crude fibre content. The heritabilily was high for total duration of the crop and crude protein content of the f r u i t . Male flowers/plan...

Studios on parameters of variability . correlation and path coefficient analysis of fruit yield in Abttmoschus caillei L- revealed that characters such as number of branches per plant, number of nodes per plant, plant height and fnlit length had maximum coefficient of variation. Higher values of heritahility anil genetic advance were simultaneously estimated for...

Heterosis for yield components and fruit characters was studied using line x tester analysis between bacterial wilt resistant / tolerant accessions and processing varieties. Heterotic hybrids were identified for average fruit weight (Sakthi x Fresh Market 9, Sakthi x HW 208F), yield / plant (Sakthi x TH 318, Sakthi x Fresh Market 9), locule number (LE 206 x Ohio 81...

The present investigation "Heterosis in snakegourd" was conducted at the College of Horticulture during 1988-1990. Assessment of genetic variability showed significant differences of 25 characters in 48 snakegourd genotypes. The highest phenotypic coefficient of variation was observed for fruiting nodes on main vine, male flowers/plant, sex ratio and fruits/plant. ...

Heterosis of growth characters and earliness in snakegourd was worked out in a 13 x 13 analysis. Heterobeltiosis and standard heterosis were found for main vine length, primary branches per plant, days to first male flower anthesis, days to first female flower opening, fruiting nodes on main vine, days to fruit maturity and days to first f r u i t picking maturi...

Bacterial wilt (Pseudomona solanacearum E.F. Smith) is a major disease of tomato. Attempts were made to improve a reportedly resistant line CL 32d-0-1-19 GS for higher fruit weight and better plant type through four selection methods – mass, pureline, single seed descent and bulk. Genetic and biochemical bases of resistance were also studied. Resistance of the evol...
