Abstract
馬鈴薯的自交，自然授粉與雜交種子，在網室中，經一個月的育苗后，移植於農業試驗所試驗田，再經三個月後採收並調查幼苗移植後在田間的成活率，單株產量及達30 g的塊莖數與總重，薯色與薯形，芽眼的深淺。以種子來生產馬鈴薯，其產量比以種薯生產者為低，但薯色、薯形與芽眼深淺等性狀的分離差異不顯著。貧瘠粘重的土壤也造成低產。
True potato seeds from various open-, self- and cross-pollinated progenies were evaluated by transplanting one-month old seedlings to two different field conditions at TART, Taichung.
Crops were harvested in 3 months and the following data was recorded on plant basis for each progeny : total tuber weight, weight and number of tubers equal to and above 30g., survival rate (% of transplants survived till harvest time), tuber skin color, shape and depth of eye. The segregation for the latter three traits was not significant in general. The highest yield obtained was 0.43 kg/pl. in comparison to 1.08 kg/pl obtained from tuber clone.
The yield was markedly reduced for both tuber clone and seedling at heavy and less fertile soil.
