“…All walnut cultivars analyzed in the present study displayed a protandrous flowering trait (Table 3). This was not a surprising result because previous studies in the existing literature pointed to the fact that 'Chandler' has a protandrous flowering trait [12,27,31]. Another study by Sütyemez [17] demonstrated that 'Maraş 18' is also protandrous in flowering.…”

“…Pollinators of 'Helete Güneşi' can benefit walnut orchards if they are planted in the right combination of male-female flowering overlap. Walnut breeding programs usually aim at higher rates of lateral bud flowering and a high abundance of female flowers, which can be considered as two important parameters in assessing yield potential in a given cultivar [12,16,28,32].…”

“…Pomological analysis helps determine fruit quality and has been widely used in many breeding studies to identify fruit cultivars with superior traits. The most important traits in a high-quality walnut cultivar are nut weight, kernel weight, kernel percentage, kernel color, kernel fill, and ease of removal of kernel halves [12,16,23,28,33,34].…”

“…High yield, early harvest date, and tolerance to plant diseases/pests are favorable traits in a good walnut cultivar. In addition, high nut quality directly boosts the market value of walnuts [8][9][10][11][12][13][14]. The main objective of walnut breeding programs is to obtain new walnut cultivars with these traits.…”

‘Helete Güneşi’ was selected among different genotypes obtained from crossing ‘Maraş 18’ × ‘Chandler’ in Turkey. The present study compares phenological and pomological traits of ‘Helete Güneşi’ with those of its parents so as to scale their performances. ‘Helete Güneşi’ staged leaf out on 22 April, whereas its parents, ‘Chandler’ and ‘Maraş 18’, did on 20 and 12 April, respectively. The harvest date of ‘Helete Güneşi’ was as early as 17 September, whereas ‘Chandler’ and ‘Maraş 18’ began to be harvested on 5 October and 15 September, respectively. Defoliation in ‘Helete Güneşi’ occurred about 1 month earlier than ‘Chandler’. The nut weight and kernel percentage of ‘Helete Güneşi’ were 13.41 g and 53.39%, respectively, whereas in ‘Chandler’ the values were 12.73 g and 48.23%, respectively, but were 14.62 g and 53.76% in ‘Maraş 18’. ‘Helete Güneşi’ had a higher yield value compared to its parents. The results demonstrated that ‘Helete Güneşi’ has superior traits in being selected for late leafing date, early harvest date, high yield, and good nut quality. Therefore, it can be considered as a valuable genetic resource in future breeding programs around the world.
