Sixty different varieties of brinjal (Solanum melongena L.) were evaluated for character association. The findings showed that the genotypic correlation was higher than the phenotypic correlation coefficient for most traits. Strong positive correlation was observed between the number of fruits per plant, branches per plant, and fruit yield per plant. Positive correlation was observed between moisture content and fruit characteristics, such as fruit volume and average fruit weight. The path coefficient analysis revealed that high positive direct effect on fruit yield was exerted by fruits per plant, followed by moisture content. [ABSTRACT FROM AUTHOR]

Twenty one crosses resulting from 7 × 7 diallel excluding reciprocal were studied to know the magnitude of heterosis over better parent and standard variety for yield and its attributing characters in rabi mungbean. The highest heterosis to the extent of 37.23% over the check Co-4 and 82.20% over the check GBM-1 was observed in cross combination Co-4 × Meha for seed yield per plant, which also exhibited high heterosis percentage for yield and yield components. The promising hybrids viz. Co-4 × Meha, Co-4 × GBM-1, GBM-1 × Meha and Rm-9-129 × Co-4 were identified which have great potential to exploit the hybrid vigour or to isolate the desirable segregants for the development of rabi mungbean varieties with chilling tolerant ability or photo-thermo insensitivity, so as to exploit potential of rabi mungbean in heavy rainfall zone as rice fallows.
