Types of seeds
बीज के विभिन्न प्रकार (Different types of seed):- ICIA (International Crop Improvement Association) के अनुसार शुद्ध बीज 4 प्रकार के होते हैं –
[According to ICIA (International Crop Improvement Association) there are 4 types of pure seeds -]
1. प्रजनक बीज (Breeder seed)
2. आधार बीज (Foundation seed)
3. पंजीकृत बीज (Registered seed)
4. प्रमाणीकृत बीज (Certified seed)
1. प्रजनक बीज (Breeder seed):-
Ø ऐसे शुद्ध बीज जिन्हें प्रत्यक्ष रूप से पादप प्रजनक की देखरेख में उत्पादित किया जाता है, प्रजनक बीज कहलाते हैं।
(Pure seeds that are produced directly under the supervision of plant breeders are called breeder seeds.)
Ø ये बीज सभी आनुवंशिक आवश्यकताओं को पूरा करते हैं।
(These seeds fulfill all genetic requirements.)
Ø ये बहुत अधिक शुद्ध व महंगे होते हैं, इसलिए बहुत कम मात्रा में उत्पादित होते हैं।
(They are very pure and expensive, so are produced in very small quantity.)
Ø इनकी आनुवंशिक शुद्धता 99.9% होती है।
(They have 99.9% of genetic purity.)
Ø इसके पैकेट पर Golden tag का उपयोग किया जाता है।
(The Golden tag is used on its packet.)
Ø कई बार प्रजनक बीज बहुत ही अल्प मात्रा में प्राप्त होता है जिसे नाभिक बीज (Nucleus seed) कहते हैं। इसके गुणन द्वारा फिर प्रजनक बीज तैयार किया जाता है।
(Many times breeder seed is obtained in a very small quantity which is called Nucleus seed. The breeder seed is then produced by its multiplication.)
2. आधार बीज (Foundation seed):-
