| Abstract:
Peach cultivation is spread over an area of about 930 hectares in the sub-tropical climate of Punjab State in India producing about 13900 tonnes of fruit annually. Shan-i-Punjab, Partap and Flordasun are the commercially cultivated cultivars. Fruits of these varieties are available from 3rd week of April to end of May. For extending the period of peach availability, eight low chilling cultivars were introduced from Florida and Texas states in the USA. After their evaluation, Punjab Agricultural University has recommended large scale cultivation of Flordaprince and Earligrande. Flordaprince gave 39 percent more yield than Flordasun. Its fruits matured in the last week of April and took 70 days from full-bloom, the average yield being 100 kg per tree. Fruits of Flordaprince were superior to Flordasun in quality and they had better firmness, TSS and TSS/acid ratio. Earligrande gave 40 percent more yield than Shan-i-Punjab. Its fruits matured slightly earlier than Shan-i-Punjab taking 73 days from full-bloom, the average yield being 95 kg per tree. Earligrande proved superior to Shan-i-Punjab and can be transported to distant markets. For other fruit traits it was similar to Shan-i-Punjab. Both varieties, Flordaprince and Earligrande, were similar to Flordasun and Shan-i-Punjab, respectively, for their reactions to various pests and diseases. | |
