Heterosis for earliness and yield contributing traits in brinjal (Solanum melongena L.)
Author(s): Maneesh Pandey and GC Yadav
Abstract: The present investigation was conducted to found out the magnitude of the heterosis in brinjal. Eight parents were crossed in diallel excluding reciprocal to developed 28 crosses. The hybrids al song with parents were evaluated in 2 consecutive years. The data were recorded on plant height, number of primary branches per plant, days to 50% flowering, days to first fruit harvest, harvest duration, average fruit weight, marketable fruit yield, which are contributing earliness and yield. For days to 50% flowering, and days to first fruit harvest maximum negative standard heterosis, and heterobeltiosis, were shown by cross combination P5 x P7 and P3 x P8, respectively. For days to first fruit harvest, high magnitude of standard heterosis and heterobeltiosis were shown by P5 x P7. For marketable fruit yield, high magnitude of standard heterosis and heterobeltiosis were shown by P1 x P8. The cross combination of P5 x P7 and P2 x P7 were found promising for earliness and yield. The cross combination utilizing inbred P1, P2, P6, and P8 were prosing, therefore these parental lines could be used for development hybrids for early and high yield.
