The object of the studies in 1977 was a population of 15 F<sub>1</sub> hybrids, 11 F<sub>2</sub> progenies and 16 parental forms (8 male-sterile A lines and 8 inbred C lines - Table 2). Variability and heritability of some onion characteristic weight, height diameter of the bulbs and their shape, collar thickness, adherence and color of dry outer skin, bulb firmness, shape of the collar and position of root disc) were studied. Variability and heritability estimates of bulb weight, diameter and shape of the collar were relatively high (30-70%).Variability of the skin thickness was also high, but heritability of this trait was low. The lowest variability and heritability were shown for bulb firmness. The high heritability of some traits indicates the possibility of increasing the effects of selection and improvement, especially of the weight and shape of bulbs.

Photosynthesis is the very essence of agriculture. Previous photosynthetic and transpirational studies of onion (Allium cepa) have been limited to specific developmental stages. Our study measured photosynthesis and transpiration in sixteen plants of a single short-day cultivar over an eleven week period containing both non- and bulb inductive photoperiods. Differences in weekly means for photosynthesis, leaf conductance, water use efficiency, and intercellular CO, were highly significant. Weekly photosynthetic means increased under a non-inductive photoperiod and peaked one week after initiating a bulb inducing photoperiod. A decrease and leveling period occurred as bulbs developed followed by a decrease as foliage lodged. Weekly photosynthetic and leaf conductance means were correlated and highly significant. Water use efficiency and intercellular CO, means remained fairly constant throughout the study suggesting that photosynthesis in unstressed onions was controlled by internal mechanisms instead of stomata.
