Seed and Spikelet phenotyping
AGW of the brown segregated lines 53-1-B and 53-3-B was significantly
higher as compared to their white counterparts (Table 7). The commercial
cultivar exhibited midrange values of AGW. Similar pattern was obtained
for SL, where this time all three brown segregated lines exhibited
significantly higher averaged values as compared to their white
counterparts (Table 7).
Coloration of the Spikelet lemma was also documented (Fig. 3). The white
commercial cultivar lemma were gray-purplish and highly transparent.
44A-163-B exhibited a dark-purple coloration and was transparent as
well. 44B-163-W exhibited bright pink lemma with whitish-gray outer
borders and veins. The brown seeded line of 53-1 exhibited much less
pink coloration (mainly at the outer borders) compared to their white
counterparts, which had bright pink lemma with white gray outer borders
and veins. The second brown line of 53-2 exhibited purple coloration at
the outer border of the lemma as compared to their white counterparts
which were pink - not purple. The third brown line of 53-3 also
exhibited purple coloration at the outer borders of the lemma as
compared to the white counterparts, which had whitish-gray lemma
(similar to the white cultivar in terms of coloration).
