Abstract:
Ten parents were crossed in half diallel fashion to get 45 F1 hybrids at Main Vegetable Research
Station, AAU, Anand during 2015-2016. Combining ability of parents and crosses were analysed
for yield and other seven characters related to earliness and quality viz., days to opening of first
male flower, days to opening of first female flower, days to first harvest, days to last harvest,
total soluble solids, total sugar content and total chlorophyll content. The magnitude of variance
due to specific combining ability was higher in comparison to variance due to general combining
ability for all the characters studied indicating larger influence of non additive genetic variance
in comparison to additive genetic variance. The predictability ratio was also found less than 0.5
for all the characters studied which further confirmed the preponderance of non-additive gene
action. The parent ACUS 13-60 exhibited the highest gca effect and the hybrid ACUS 13-60 x
ACUS 9-51 depicted the highest sca effect for fruit yield per plant. |
