Yield component analysis of 'Harrow Delight', Kieffer', and 'Harvest Queen' pear
1990
Kappel, F.
Yield components of 8- to 10-year-old trees were compared among 'Kieffer' [Pyrus communis (L.) X Pyrus pyrifolia (Burm.)] and 'Harrow Delight' and 'Harvest Queen' [Pyrus communis (L.)]. 'Kieffer' set more fruit than the other cultivars, even though flower density was similar. 'Kieffer' also had similar size or larger fruit than 'Harrow Delight' or 'Harvest Queen'. Path analysis showed that the direct and indirect effect of fruit number on yield was important for all cultivars. Flower density only had a small direct effect on yield and this was at times negative. Fruit size had a small effect on yield when compared to fruit number.
