Abstract:

Understanding complex factors controlling yield is very crucial to the improvement of plant performance. Cashew (Anacardium occidentale L.) is an important nut crop of social and economic importance for India. The low productivity of raw cashew nut is the major constraint. As detailed morpho- physiological characterization is one of the key steps for yield improvement, this study was carried out to analyze genotypic variation in yield and yield components of fifteen cashew accessions. Here, we relate leaf morphological traits of fifteen cashew varieties to their nut yield and other yield components. Significant differences in leaf morphological and physiological traits observed among cashew accessions. The specific leaf weight was maximum in Vengurlla-3 and Vengurlla -4. The content of chlorophyll a and total chlorophyll was highest in Bhaskara whereas Selection-2 had highest total carotenoid content. The total number of hermaphrodite flowers, sex ratio and total number of flowering panicle was highest in Kanaka, Selection-2, Ullal-2, Ullal-3 and Vengurlla-4 respectively. The nut and kernel weight were highest in Priyanka whereas nut yield and shelling percentage were maximum in Ullal-1, Bhaskara and Ullal-2. Associations between yield traits and leaf morphological traits showed that leaf area (LA), specific leaf area (SLA) and specific leaf weight (SLW) can be regarded as primary yield attributing traits to improve nut yield through increase in nut number per tree, nut weight and panicle number per tree. Therefore, we conclude that leaf morphological and physiological traits are important not only for species identification but also for genetic divergence to improve plant performance influencing yield.
