Sample size for the evaluation of selection traits of nuts in hazelnut varieties

Planning works on the study of coblnut (hazelnut) requires establishing sample size, taking into account magnitude error and significance results. Such studies have not been carried out in full with regard to plant varieties, modern requirements. The purpose research is determine size for calculating value selection traits nuts hazelnut varieties different rates levels. For this 12 main economically valuable breeding studied 8 – taste, weight, indestructibility, kernel yield, presence husks it, strength color shell, nut one-dimensionality fruits shape, overall score. A well-known method has used calculate evaluating each indicator relative absolute errors levels significance. largest contribution maximum score 59 points made by core indicators: taste 25.42%, weight 22.29%, indestructibility 16.9%, yield 11.31%. share other features estimated at 2.25 6.78%. a estimate 5% accepted Biology indicators was level α = 0.05 / 0.1: walnut 30/21, 43/30 nuts; scoring shell 18/13, 22/16, 137/95, 27/19, 25/17, total category 11/7 nuts. expressed as percentage 0.05: an 1% 98, damaged diseases, pests 10% 62, one-dimensional 57, shape 10%, 54 hazelnuts.
