ABSTRACT

A diallel analysis in mungbean carried out from a set of 36 genotypes comprising of 8 genotypes
and 28 F1 crosses were sown in randomized block design with three replications. The highest
heterobeltiosis of 62.50 per cent was recorded by cross PDM-87 x K851. The crosses PDM-143
x GM3 registered the highest standard heterosis (36.90) for seed yield followed by PDM11 x GM-
4 with standard heterosis (30.95). These crosses also showed significant standard heterosis for
the component trait like pods per plant and days to 50 % flowering. The cross PDM-143 XPDM-
87 noted highest standard heterosis and followed by PDM-143 X PDM-11 for early flowering. The
crosses PDM-11 x GM-4, PDM-11 x GM-9918, PDM-143 x GM-9918 and PDM-87 x K-851
manifested relatively high heterobeltiosis, though their mean yields were higher as compared to
high x high and low x low crosses. The magnitude of dominance was higher than additive
component. In case of days to maturity, branches per plant, seed yield per plant, 100-seed weight,
protein content and YMV incidence at least one gene or gene group exhibited dominance.
This cross can be used for direct selection in segregating generation for isolation of superior
homozygous lines.
