Abstract
Studies on crop improvement in guava (Psidium guajava L.) by selection of open pollinated seedlings progenies of Apple Colour cultivar was initiated in 272 six-year-old seedlings grown in farmers field at Ramanagara taluk of Bangalore Rural District, Karnataka.
These 272 seedlings were short-listed to ten seedlings based on attractive and bright red colour of skin along with superior fruit quality.
Studies on these ten open pollinated progenies of guava revealed that A.C.Seln. 6/10 was an outstanding one with dwarf stature (1.98 m), moderate yield with medium to large sized fruit (143.43 g), attractive shape, good volume (165.28 ml), high TSS (13.80ºB), moderate acidity (0.37% citric acidity) and high ascorbic acid (194.85 mg/100 g) content.
The total sugars (8.27%), reducing sugar (4.46%) and non-reducing sugar (3.80%) were also high in this selection with moderate to good sugar/acid blend (22.10). The fruits are very attractive, uniformly bright red in colour with lycopene pigment of 3.61 mg/100 g of fruit.
The fruits fetch the highest score in characteristics such as peel colour (13.45 out of 15), pulp colour (12.20 out of 15) and the organoleptic taste of pulp (22.30 score out of 30). Further, the overall acceptance of the fruit for organoleptic qualities was also highest (79.03 score out of 100). Hence this selection could be utilized for commercial cultivation.
