| Abstract:
This investigation was carried out in order to evaluate and compare 11 almond cultivars in Emamie station at Chaharmahal va Bakhtiari province. The experiment was done a in randomized complete block design (RCBD) with 3 replications. In the first stage trunk diameter, tree height and annual shoot growth were evaluated. Trunk diameter did not show any significant differences but annual shoot growth and tree height showed significant differences among cultivars at 1% level. Cultivars, 12, 18 and 15 had the longest shoot length and 12, 13, 15 and 18 had the highest tree height. Three years’ evaluation of cultivars’ reproductive characteristics showed differences in blooming date, fruit and kernel yield, characteristics of fruit and kernel. On the basis of visual scale, relative resistance to some important pests was different. Sefid was the earliest blooming and 16 the latest blooming cultivar (with 4 weeks difference in full bloom). 15 had the earliest crop maturity while Shahrood17 had the latest crop maturity. Fruit and kernel yield were significantly different (at 1% level) among cultivars. 12, Rabi and 6 had the highest yield and Sefid, 18 and 16 had the lowest yield. 18 and Rabi had the highest (75%), and the lowest (30%) kernel percentage respectively. 12 and 6 had the lowest (0%), and Mamaie had the highest (64%) double kernel fruits. Observations showed that for cultivar 12 leaves, infection with aphids occurred at a very low level while Mamaie and Rabi were infected at a high level. 12 and Mamaie branches and scaffolds infected at a very high level with Pterochloroides persica 6 and 12 are resistant to almond red leaf blotch disease while Mamaei, Rabi, Sefid, 16 and 13 are susceptible. Damaged nuts with Eurytoma amigdali in 13, 17, 18 and Sefid were at a very high level but infected fruits in 12 were at very low levels. | |
