Studies on combining ability for leaf area, specific leaf weight and chlorophyll content in field pea.

摘要

Combinig ability analysis for six physiological characters in pea (Pisum sativum L.) revealed leaf area and chlorophyll-a/b ratio was governed by additive gene action. While both additive and non-additive gene actions were important for controlling total chlorophyll, chlorophyll-a, chlorophyll-b contents and specific leaf weight. Lines HPPC 41, HPPC 77, HPPC 91 and HPPC 94 for leaf area and total chlorophyll content and HPPC 60, HPPC 67 and HPPC 84 for specific leaf weight were food general combiners. While HPPC 67 x HPPC 63, HPPC 69 x Lincoln, and HPPC 94 x Lincoln were the promising crosses for specific leaf weight, chlorophyll-a and chlorophyll-b contents, respectively, on the basis of specific combining ability.
