Walnut cultivars through cross-breeding: 'Diriliş' and '15 Temmuz'

This study considered two new walnut cultivars ('Diriliş' and '15 Temmuz') and aimed to evaluate their performance, phenological and pomological traits. The cultivars were obtained through cross-breeding in Turkey. The phenological and pomological traits of mature trees of the cultivars 'Diriliş' and '15 Temmuz' were compared with those of 'Pedro', 'Chandler' and 'Maraş 18' cultivars. Late leafing and a high level of lateral fruitfulness were the most prominent plant traits of the new cultivars 'Diriliş' and '15 Temmuz'. The nut weight, kernel weight and kernel percentage measured 13.70g, 7.23g and 52.83% in the 'Diriliş' cultivar, and measured 14.32g, 7.72g and 53.92% in '15 Temmuz' respectively. Results indicated that these new cultivars have good performance, with phenological and pomological traits that are better or comparable to common walnut cultivars.
