3.step one Phenotype
I amassed phenotypic research regarding Vida/MTHW0202 RIL population and you can moms and dads person in the around three rainfed as well as 2 irrigated surroundings in the 2013?2014 increasing year. Table step 1 account function categorized toward shared, rainfed, and irrigated environments for a couple characteristics that have been built-up in the moms and dads and RIL society. The new rainfed grains yield RIL suggest is actually thirty five% lower than new irrigated RIL grain produce imply. While doing so, rainfed produce component attributes try lbs, thousand-kernel weight, and you will seed products number each direct was indeed 4, seven, and you can eight% less than the fresh new irrigated surroundings, correspondingly. In contrast, effective tiller count produce component RIL imply was 8% large regarding the rainfed environment compared to the irrigated environments.
- Mention. GLDAH, environmentally friendly leaf course after heading, a description of remain-green attribute.
- * Significant difference one of RIL moms and dads and you can RIL records on .05 opportunities peak.
- ** Significant difference one of RIL mothers and RIL records on .01 opportunities level.
- *** Factor certainly one of RIL best hookup apps Waco moms and dads and you may RIL entries on .001 possibilities top.
Grain yield among parents was significantly different (P < .05) in only the rain-fed environments where Vida's grain yield was 6.0% higher than MTHW0202. MTHW0202 had significantly higher (P < .05) seed diameter and seed number per head across, rainfed, irrigated, and combined environments. Vida had significantly higher productive tiller number (P < .01) vs. MTHW0202 in all environments. Vida also had significantly later heading date (P < .001) and maturity date (P < .05) vs. MTHW020 across combined, rainfed, and irrigated environments, but GLDAH was not significantly different among parents in any environment. Thousand-kernel weight was significantly higher (P < .01) in MTHW0202 vs. Vida in the combined and irrigated environments. Vida was significantly taller (P < .05) than MTHW0202 in the combined and rainfed environments.
Significant differences among RIL entry means were also observedbined environment RIL entry means were significantly different for test weight (P < .001), thousand-kernel weight (P < .001), seed diameter (P < .001), seed number per head (P < .001), heading date (P < .001), GLDAH (P < .05), maturity (P < .05), plant height (P < .001), and grain protein content (P < .001) (Table 1). Significant differences among RIL entry means were also observed for thousand-kernel weight (P < .001), seed number per head (P < .001), plant height (P < .001), and grain protein content (P < .001) in rainfed environments. Plant height RIL entry means were significantly different (P < .001) in the irrigated environments. Transgressive segregation was observed in the RIL population for all traits in the combined, rainfed, and irrigated environments, except for GLDAH in the irrigated environments and maturity in the rainfed environments.
step 3.2 Correlation data
Pearson correlations between traits varied among environments. In the rainfed environments, GLDAH was positively correlated with yield (P < .001, r = .37), test weight (P < .001, r = .47), and thousand-kernel weight (P < .001, r = .38), but was negatively correlated with seed number per head (P < .05, r = ?.20) and heading date (P < .001, r = ?.36) (Table 2). In irrigated environments, GLDAH was positively correlated with test weight (P < .01, r = .25) and thousand-kernel weight (P < .01, r = .24), but was not significantly correlated with yield (Table 2). Seed number per head (P < .05, r = ?.20) and heading date (P < .001, r = ?.39) were negatively correlated with GLDAH in irrigated environments (Table 2). Yield was positively correlated with test weight (P < .001, r = .36) and thousand-kernel weight (P < .01, r = .24), but was negatively correlated with heading date (P < .001, r = ?.31) in rainfed environments (Table 3). Yield was positively correlated with seed number per head (P < .001, r = .33), heading date (P < .05, r = .19), and productive tiller number (P < .001, r = .29), but was not significantly correlated with test weight and thousand-kernel weight in irrigated environments (Table 3).
