Selection of Superior Genotypes in 37 Clones of Camu-Camu by Repetitivity Analysis | Chapter 01 | Advances and Trends in Agricultural Sciences Vol. 3
In order to select camu-camu superior
genotypes, a comparative of clones from natural populations, farmer plantations
and an experimental field of the National Institute of Agrarian Innovation
(INIA), was established in 2004 in varzea, at the Peruvian Amazon Research
Institute (IIAP). Nine harvests between 2006 and 2016 have been evaluated,
including variables in vegetative and reproductive development states.
Statistical analysis was performed using the SPSS program for analysis of
variance and SELEGEN REML/BLUP for repetitivity analysis of “fruit yield” (FY)
and “fruit weight” (FW) with 5 and 4 measurements (years) respectively. For FY,
a repetitivity index r = 0.117±0.07 was obtained with a selective precision of
0.63 and efficiency of 1.84 where clones 69, 48, 58, 50, 61, 13, 18, 29, 49 and
32, were selected in descending order of merit. For FW, r = 0.690±0.294 was
obtained with selective precision of 0.948, efficiency of 1.14 and selection of
clones 44, 13, 26, 23, 69, 64 22, 52, 27 and 8. As for the content in ascorbic
acid, clones 48, 32 and 35 occupied the first places with more than 2000 mg of
ascorbic acid/100 g. The selections achieved strengthened the pre-improvement
work by conferring vigoury fiavility of a long term research.
