Yerel\/yerli ya da \u00e7ift\u00e7i \u00e7e\u015fidi nedir?<\/strong><\/p>\n

Yerel \u00e7e\u015fitlerin tohumu da yerel tohum. Anadolu t\u00fct\u00fcn, domates, biber, fasulye, m\u0131s\u0131r, patates ile sonradan tan\u0131\u015fmas\u0131na ra\u011fmen bu \u00fcr\u00fcnlerde b\u00fcy\u00fck bir \u00e7e\u015fitlili\u011fe sahip.

Hibrit tohum nedir?<\/strong><\/p>\n

Birle\u015ftiklerinde istenen karakterleri ortaya \u00e7\u0131karan gen kombinasyonunu sa\u011flayacak bireyleri verecek olan ebeveynler aras\u0131ndaki birle\u015fme sonucu olu\u015fan bireylere \u201chibrit\u201d deniyor.<\/p>\n

Yerli \u00e7e\u015fitlerden elde edilen \u00fcr\u00fcnleri talep etmek ayn\u0131 zamanda hem besleyici de\u011feri hem de lezzeti istemek anlam\u0131na geliyor.

Yerli \u00e7e\u015fitler, geli\u015ftirilmi\u015f \u00e7e\u015fitlere g\u00f6re daha az su ve g\u00fcbre kullan\u0131yor.
