| Abstract:
Out of 272 open pollinated seedling progenies of ‘Apple Colour’, ten seedlings were selected based on their growth, yield and fruit quality attributes and with special emphasis for the development of bright red coloured skin. Of these ten seedlings, A.C.Seln.10/2 recorded maximum plant girth and height while it was least in A.C.Seln.6/10. Fruit yield was highest in A.C.Seln.10/3 (13.62 kg/tree) closely followed by A.C.Seln.10/2 (11.64 kg/tree) while yield was lowest in A.C.Seln.6/6 (5.28 kg/tree). Fruit weight was maximum in A.C.Seln.2/11 (176.76 g) followed by A.C.Seln.5/5(147.61 g), 6/10 (143.43 g) and 10/3 (129.18 g). Highest total soluble solids (13.80◦B), ascorbic acid (194.85 mg/100 g), total sugars (8.27%) and lycopene pigment (3.61 mg/100 g) were noticed in A.C.Seln.6/10 and the fruits of this selection had less number of seeds (142 seeds) and titratable acidity content was moderate (0.37% citric acid). On the basis of yield and fruit quality attributes A.C.Seln6/10 was found to be best for commercial cultivation. A study of correlation among different yield contributing characters, the trunk girth was positively and significantly associated with fruit yield. | |
