dc.description.abstract |
Mode of inheritance and allelic relationships of genes conforming resistance to gall midge {Orseolia oryzae
Wood Mason) were investigated in four rice {Oryza saliva L.) genotypes viz. ARC 5984, ARC 6619, RP 2068-
16-4-5 and R-296-421-2. Inheritance studies revealed presence of a single dominant gene for resistance in
ARC 6619 and R-296-421-2, whereas resistance to gall midge was found to be governed by a single recessive
gene in ARC 5984. Two independent dominant genes for resistance were observed in RP 2068-16-4-5.
Susceptible parent R-2270 was found to possess a single dominant gene for resistance along with an
inhibitory gene, which inhibits manifestation of resistance. Allelic tests also confirmed the presence of a
recessive gene for resistance to gall midge in ARC 5984. This recessive gene was non-allelic to Gm-1
(Samridhi) and Gm-2 (Surekha). ARC 6619 was found to posses the same gene for resistance as present in
Surekha (Gm-2). Out of the two independent dominant genes conferring resistance in RP-2068-16-4-5, one
was found to be allelic to Gm-1 (Samridhi). The single dominant gene present in R-296-421-2 was non-allelic
to Gm-1 and Gm-2. |
