Parentage validation for certain hybrids of mango (Mangifera indica L)
Author(s): Nesara Begane, MR Dinesh and KV Ravishankar
Abstract: The mango is highly cross-pollinated and heterozygous. It has delicate flowers and the fruit set is only about 0.01% (8Iyer, 1991). In the absence of morphological markers, it is extremely difficult to make out whether the resultant hybrid progenies are from the parents, which were utilized for crossing or not. The morphological observations recorded shows that the colour of the variety ‘Sensation’ and Janardhan Pasand as male parent imparts young leaf colour (reddish brown) to the hybrid. The hybrid Arunika, also had a colour similar to its male parent ‘Vanraj’. These results help in developing pre-selection indices for progeny selection. The molecular characterization of thirty-eight hybrids carried out with eight SSR (Simple Sequence Repeat), revealed paternal allele inheritance for the hybrids Arka Udaya, Konkan Ruchi, Manjeera and AU-Rumani to the extent of 50, 50, 54.54 and 50%, respectively. The five hybrids viz., Arka Anmol, Arka Udaya, Konkan Ruchi, Manjeera, AU-Rumani were confirmed for their parentage by the allele transmission from parents to offspring. The validation of hybrids using total phenolics and flavonoids indicated both paternal and maternal inheritance.
